The momentum of the one marble rolling down the ramp before the collision should be equal to the sum of the momentums of the marbles after the collision. 1. Use an if you need to show that the car is moving. Department of Physics and Astronomy | University of Mississippi From this measurement (and its uncertainty), determine the k factor of the ball (and the uncertainty on k). 8. If you allow the ball to travel for twice as much time (or distance), its velocity will. Neglect air resistance and spin on the ball. To observe a more significant affect from air resistance, repeat the ball tossing experiment three times, this time using a beach ball or other very light, large ball. 5) When the ball reaches the 20 cm. the edge of the track. Set This ball has potential energy because of its height. Lab 2 – Blowing Marble Materials: 1 straw, 1 golf ball, 1 marble Procedure: 1. If it is lifted higher, it will have more potential energy. This lab showed us how distance and time is present as a ball is rolling down an inclined ramp. There should already be 20 cm. In doing this lab, I hoped to learn the position, velocity, and acceleration of a gently pushed cart on a ramp. Q1. Pull the cart at an angle of 60o to the surface of the ramp (!!). Launch the ball from a certain height on the ramp. Step 15: One student should mark the position of the ball on the ramp while the Projectile Motions Lab Conducting the Lab Our lab was conducted by letting steel balls go at the top of the ramp, which basically is almost zero velocity at the top of the ramp. The ball's acceleration gets closer to the acceleration of gravity as the slope gets more and more steep. PROJECTILE MOTION e The ball will strike the ground 1.0 s after it is PRACTICE QUESTIONS (WITH ANSWERS) struck. Ball And Ramp Lab Answers 1/20 Downloaded from oos.mylearning.gemseducation.com on February 15, 2021 by guest Kindle File Format Ball And Ramp Lab Answers This is likewise one of the factors by obtaining the soft documents of this ball and ramp lab answers by online. Try blowing the marble at different angles. 0.04 m/s. marks on the incline. 5. Acceleration is equivalent to the slope of velocity. As the angle of the ramp increases the acceleration of the ball increases. c) Setup the ramp, cart, force probe as seen below in the figure. In lab this week, we will create and analyze cases of static equilibrium like in the sample problem to the right. If the ramp is vertical, the ball just drops with acceleration due to gravity. C. Angular Momentum Toys of 6 bounces of a super-ball. When the marble is at rest what happens? This ball has kinetic energy as it falls. 61 m/s The questions refer to a ball starting at rest and falling, or rolling down a straight ramp as shown. Sketch your setup in your lab book with the dimensions labeled. Collect Materials 2. • measure h, H, s, and s1. 4) Repeat for a total of 3 trials for each object. You will record the time it takes the ball to roll down the incline every 20 cm. Let us assume, for argument’s sake, that the ramp is at a convenient slope such that, after rolling down it for one second, the ball is moving at two meters per second. Data: 1. % Eff. 3. In this case, the ramp angle is the independent variable (the one you can change) while Thus, at the end, there are 3 bars of momentum in total for the person (system). Let's say you have a ramp and a ball. You will need to have one person observe the larger ball and one person observe the smaller ball. If you tilt the ramp at a certain angle and roll the ball down the ramp, the ball will roll at a certain speed. Choices on the left. Let the ball start rolling from 0 cm. Record how high EACH ball bounces when you do this. 6. Repeat with the golf ball. Release a ball near the bottom of the ramp so it strikes the magnet slowly and causes the Gauss Gun to fire. 3) Record the time it takes the objects to roll the entire length of the ramp - from “Start” to “Finish (2.7 meters). Mr. S. sets up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. Then place a sheet of carbon paper (ink side down) on the paper where the ball will land. 1) You will need 5 ball bearings of different sizes. 2. Newton’s First Law of Motion tells us the ball would travel in a straight line forever unless a force acts on the ball. Question 1 Phenomena Test 1: Size of ball a) Prediction: If we roll two different sized balls down the inclined plane at the same time, 1. Try to keep the smaller ball in contact with the larger one. The marble coming into the collision is called the "inbound" marble in this laboratory. To make measurements use LoggerPro and the same video analysis procedure used in Experiment 6 in the lab manual. Questions to Ponder and Answer 1. Let the ball roll off the incline. Answer: 6.28 or 2π ... transfer of PE to KE of a golf ball rolling down a ramp. This is an important quantity since the computer uses it to calculate the launch velocity of the ball. The answer, of course, is gravity. Place the two motion gates at the end of the ramp directly one after the other. answer choices 53 m/s. What is the acceleration of a ball rolling down a ramp that travels 1.2 m in 2 s? If the ramp is horizontal, then the ball does not accelerate, as gravity pushes the ball into the ramp and not along the surface of the ramp. d) Zero the force probe. e) Find the force needed to pull the cart up the ramp at a constant velocity for the following cases: i. Getting to the Core Grade 8 Unit of Study STUDENT RESOURCE Roller from potential and kinetic energy roller coaster worksheet , source:docplayer.net. A tennis ball is shot horizontally from a cannon at a height of 5.0m. - Ball bearing - Ramp - Electrical tape - Carbon Paper Procedure: 1. Why? The ball will hit the … All pulls or pushes are called forces. The ball used in this lab is large enough and light enough that air resistance may affect the acceleration in a small way. roll down an inclined plane faster than lighter rolling objects. Our results may have been attributed mostly to the fact that heavier objects are more resistant to air resistance. I'd say I was successful. If you make the angle of the ramp steeper, the ball will roll faster. Solution for The potential energy of a 40-kg cannon ball is 14000J. Place the marble on the table. 1. This means that after two seconds it would be moving at four meters per second, after three seconds at six meters per second and so on until it hits the end of the ramp. 27 m/s. 45 m/s. INTRODUCTION In this laboratory I’m going to relate the time that a ball needs for 6 bounces from different dropping heights. Place ramp upright on the desk. decrease. In the ramp lab, one of the ramps had a slight bow to it and the data collected took an odd shaped curve unlike the data collected by other groups. ii. You … We will write the moment of inertia in a … Unformatted text preview: Experiment 1 Distance Traveled by a Projectile In this experiment you will use kinematic equations to predict the range of a projectile set in motion To do this you will roll marbles down a ramp and off a table to observe vertical and horizontal motion Materials Sheet of Carbon Paper 1 Fishing Sinker Masking Tape 1 Marble Monofilament Line 1 Protractor 1 Ramp … The independent variable is the dropping height H because I … So a force must be acting on the ball. 4) Start with the ping pong ball. 7. Rotational Motion and Ramp Lab_web.pptx The correct answer is A, because the person's initial momentum is positive, the medicine ball gives a positive impulse to the person, so there's about one bar of impulse added to the system. Record the data for each case and … My variables are height, time for bounces, mass of ball, bouncing surface and number of bounces. The sphere The ring The disk Three-way tie Can't tell - it depends on mass and/or radius. Use a vernier caliper and measure the diameter of the ball. Launch the cart with the same ramp angle and initial velocity that you've been using throughout the lab. V = distance/time A ramp- This can be made using items on hand at the time, for example you could create one by stacking books A heavy ball and light ball- For the lab two balls with different weights will be rolled down a ramp. Explain your answer. 5) Determine the velocity of the object. 5. 3. I learned that if you were to increase the distance and make the incline of the ramp steeper, the velocity of the ball would be highly affected- in the sense that it would increase. How long would the golf ball be in the air if we had used a ramp where the inclined part was twice as long? Ramp Ramp Floor Floor Draw a on the picture below, where it would have the most kinetic energy. Prior to this week's lab be sure to 1) Watch the two videos to the right, 2) Watch my Pre Lab video below, 3) Explore the simulation as described in the video, and 4) Complete the pre-lab quiz on Blackboard. Always? If the ball reaches the end of the ramp more than 0.2 s after 5.0 s, increase the angle between the floor and the ramp. 4. Then vx = 20 m s–1 * challenge questions and vy = 0 + (9.8 m s–2) (1.0 s) = 9.8 m s–1 The speed of the ball at 1.0 s is given by: [ (20 m s–1)2 + (9.8 m s–1)2] ½ = 22.3 m s–1 Q2. stay the … Measure the distance between the centres of both of the motion gates and record the number. The green vector arrow represents the velocity. 4. Notice how it continues to change in magnitude and eventually direction, starting from full length, going up the ramp to zero length, and then pointing down the ramp and … Make sure ramps are secured firmly in place for each trial. Use Newton’s Laws of Motion to explain what happens. Ask the instructor or the lab assistant to show you how to enter this number in the computer. Ignore friction and air resistance. Take note of where the launched ball lands on the floor, and tape a sheet of white paper in that spot. Identify the INDEPENDENT variable. If the ball has a range of 110m, calculate the horizontal velocity of the tennis ball. The lab uses a golf ball and ping pong ball, however other items can be substituted based on … Pull the cart parallel to the ramp (!!). After the train coasts to the conclusion of the track, the energy reservoir is all but empty. • measure mass and radius of the ball. You can roll a ball down a ramp, and it will pick up enough speed to “loop the loop.” Determine experimentally the minimum height h such that the ball loops the loop without leaving the track. The acceleration is .22823m/s/s, and the slope of the velocity graph is … 2. 4. stop your timer. Start your timer. A video of the motion of the ball is provided for you on eclass or my website. The limit for the balls acceleration is the acceleration of … How high was the cannon ball to have this much potential energy? Choose one of the following questions and write your answer using complete … decrease the angle between the floor and the ramp. Blow through the straw directing air at the marble. From the ramps top we count down and release, which at the same time we start counting time and stop at the time when I hear the ball hit the floor. 2) Record the mass of each ball bearing below. But what force? Did the group using that ramp take bad or good data? The pull of gravity between the Earth and the ball causes the ball to drop. How closely does the slope correspond to the acceleration?
