4. Review: Notes Free Fall: A situation where the only force acting on an object and causing it to accelerate is gravity. Acceleration due to gravity: – On Earth the acceleration due to gravity is 9.81m/s/s

5. Calculating g We can calculate g by using the following formula: x = the drop height t = the time until impact

6. 1. Record this data in your notebook: Drop Height: ______meters 2. Calculate g (show your work)

7. Wrapping Up… A elephant and a mouse are dropped from the top of the Empire State building at the same time. Which one will hit the ground first? Why?
