Finding the Acceleration of a Ball Problem Statement: How does the height of a ramp that is comprised of two parallel rulers affect the speed of a steel ball bearing rolling down it? Hypothesis: If the steepness of the ramp based on the amount of books propping it up are increased‚ then the steel ball bearings’ speed will increase. Materials: 2 wooden meter sticks 1 steel ball bearing 5 workbooks A roll of masking tape A stopwatch A smooth‚ long surface (preferably a table) Procedures: Arrange

The Effects of Force and Mass on an Object’s Acceleration Abstract: In this lab there were two principals investigated. The first was the relationship between applied force and acceleration. The second was the relationship between mass and acceleration. To study these two relationships‚ my partners and I used a dynamic cart with added mass on it. This cart was then attached to a pulley system on a “frictionless track” where it was pulled by a string bearing mass over the edge

The point where the centripetal acceleration is provided completely by gravity is when the centripetal acceleration is equal to the gravity. This happens at the point where h=r/2. As the truck moves from point A to point B‚ it would have decreased in height by r. Applying this again to our equation‚ we get; Hence‚ Using this in our g-force equation‚ we get; And so the rider experiences an additional 2g of centripetal force from that experienced at the top. Later‚ as the tuck moves to point

Free-Fall Acceleration Introduction Galileo Galilei (1564-1642)‚ the man first accredited with the correct notion of free-fall with uniform acceleration‚ stated that ’if one were to remove entirely the resistance of the medium‚ all materials would descend with equal speed.’ Today‚ this statement holds true for all objects in free-fall near the Earth’s surface. The purpose of this experiment is to verify Galileo’s assertion that acceleration is constant. In addition‚ the magnitude of acceleration will
