1. Warm Up

2. Warm Up – Another way A race car is slowed with a constant acceleration. The car is traveling 55 m/s initially and travels _______ meters before it stops. Determine the acceleration of the vehicle.

3. Third Warm up

4. Physics Honors C – Day 09/11/15 C - Day Lab 1

5. Free fall

6. Example Problem If you drop an object from 2m above the ground, what will be the velocity when it hits the ground?

7. Closing questions ▪If a feather and a hammer were to fall in a vacuum (a regiond with no air) would they hit the ground at the same time? Feather and hammer in space

8. Lab Experimentally derive the value for gravity using materials and kinematic equations.

9. Standard Deviation ▪ Some experiments have intrinsic error Solution: Repeat experiment Error in measurement would be the standard deviation
