Mini-Quiz: Gravity Time Equations for Falling Objects

by Ron Kurtus (revised 5 January 2011)

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

1. How long does it take a falling object to reach 196 m/s?

2 minutes

200 seconds

20 seconds

2. How long does it take a falling object to reach 19.6 m?

2 seconds

4 seconds

8 seconds

3. How long does it take a falling object to reach 196 ft/s?

20 seconds

6.125 seconds

3.98 seconds

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.
