Unformatted text preview: constant acceleration situation.
Acceleration due to gravity = 9.8m/s2 Practice Problem:
Practice Problem: A rock is dropped from the top of a cliff. It takes 5 seconds to hit bottom. How high is the cliff? Practice Problem
A bottle is dropped from a 100 meter building. How fast is it going when it hits the ground? Wile E Coyote slips and falls off a cliff. He hits the bottom with a velocity of 30 m/s. How high was the cliff? Picket fence freefall lab
Picket fence freefall lab Problem: to measure the acceleration due to gravity to .5% precision. Precision vs Accuracy Precision vs Accuracy Uncertainty: (MaxMin)/2 Precision:
uncertainty/average x 100
Accuracy: Error %= measured – actual x 100
I own/I don’t understand Out:
What do you need to remember about freefall?...
