Forces in Motion - Lesson 1

Match it! Select the correct answer from the pull down...Good luck!

If three balls of different matrials were dropped at the same time form the same height, which would hit the ground first? (Assume there is no air resistance.)

An object is in projectile motion if

An orbit is formed when the shuttle

All objects accelerate toward the Earth at a rate of 9.8 m/s/s. This means that for every second that an object falls, its downward velocity

A feather and a rock dropped at the same time from the same height would land at the same time when dropped

The amount of air resistance acting on an object depends on the object's

Air resistance is

A ball is dropped from a rooftop. What is the ball's velocity after 3 s? (Assume that there is no air resistance)
