# Mini-Quiz: Gravity Velocity Equations for Falling Objects

by Ron Kurtus (revised 5 January 2011)

Take this Mini-Quiz to check your understanding of the lesson material.

1. What velocity in m/s does an object reach in 10 seconds?

0.98 meters/second

9.8 meters per second

98 meters per second

2. What is the velocity of an object after it has fallen 400 feet?

160 ft/s

80 ft/s

400 ft/s

3. If an object falls for 3 s, which velocity is greater: 29.4 m/s or 96 ft/s?

96 ft/s is greater, because 96 is more than 29.4

29.4 is greater, because meters are larger than feet

They are the same velocity, except with different units of measurement

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
