Equal+Time

__Equal Time__ Equal Time (Show your calculations for #1)



Answer the following: 1. If an object falls, how fast will it be going after one second, two seconds and three seconds. A x T = S 2. Predict how the impact speeds of the three washers will differ when they hit the floor. 3. Predict the spacing between the sounds made by the washers as they hit the floor for both the evenly spaced string and the increasing spaced string. (The time between the first and second impact sounds was …… than the time between the second and third impact sounds.) (more, less, same) 4. Test the increasing spaced string. Conclusion: Describe the spacing between the sounds you heard and explain why this spacing occurred.

Galileo did a similar experiment but he slowed the falling down by using a ramp. He listened for speed bumps.
