Notes on Gravity:
On your own paper, and IN COMPLETE SENTENCES, answer the following questions (or write the question) from the slides above:
1) What is gravity?
2) What is weight?
3) Why do you fall “down”?
4) How is gravity affected by the distance between two objects?
5) How is gravity affected by the size (mass) of an object?
6) What is free-fall?
7) What is the acceleration of a free-falling object?
8) Typically, what two forces affect a falling object?
9) What is air resistance?
10) If dropped, does a crumpled or flat piece of paper reach the ground first? Why?
11) Which direction does air resistance act?
12) What does the amount of air resistance on an object depend on?
13) What is responsible for the difference in the falling speed of objects?
14) What is terminal velocity?
15) Why does a parachute help a sky diver land safely?
