Marble Rolling Down A Ramp Experiment

The marble speeds up on its way down the ramp.

Marble rolling down a ramp experiment.

Taten williams luke kelly and jack ambrose. Finally you push a marble on a ramp that represents the middle state between the first two in other words a ramp that is perfectly horizontal. After many trials he observed that the amount of time it took for the ball to roll down the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance. Long cardboard tube such as an empty roll of wrapping paper to make your ramp.

Suppose you start the marble at rest xe 0 m s and it travels a distance of d. But if you did this same experiment on a flat surface the marble would barely move right it is gravity that is pulling the ball down the ramp. It starts to roll faster and faster down the ramp right. Find more round objects spheres or cylinders that you can roll down the ramp.

It slows down as it goes up. Investigating the speed of a marble rolling down a variable ramp introduction in this experiment i am going to investigate the speed of a marble rolling down a variable ramp. Set up the ramp with h 0 10 m above the table as shown in figure 1 2. I predict that the steeper the ramp the faster the marble will travel.

See making measurements above. So that marble teetering at the top of the ramp has the potential energy of gravity which is the force that will pull it down the ramp. My two hypotheses suggested that the surface texture of an inclined ramp would affect the distance traveled by a marble rolled down it and that the less textured the ramp s surface was the farther the marble would roll. In this experiment you will roll a marble down a ramp to find out.

Average calculated on rolls 2 3 and spare roll. Using a water clock galileo measured the time it took for the ball to roll a known distance down the inclined plane. The input variable is the height of the ramp so i will keep everything the same except this factor. Use 1 d kinematics to predict the velocity of the ball xi at the bottom of the ramp.

It should be at least two and one. Now you give a gentle push to the marble going uphill on the second ramp. Starting with the cylinder at rest use the stopwatch to measure the time to roll distance d 1 0 meter down the ramp.
