Unit 2: Forces at a Distance

Gravity

It’s a good thing this mountain climber’s safety gear is working, because it’s a long way down to the ground! If he were to fall, he’d be moving really fast by the time he got there. The higher any object starts falling from above Earth’s surface, the faster it’s traveling by the time it reaches the ground. Do you know why? The reason is gravity.

FORCE = MASS X GRAVITY (9.8 m/s2)
