# Mini-Quiz: Gravity Displacement Equations for Objects Projected Downward

by Ron Kurtus (revised 7 January 2011)

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

1. If you throw an object downward at 8 ft/s, how far does it travel when it reaches 20 ft/s?

20 feet

5.25 feet

2 feet

2. If you throw an object downward at 10 m/s, how far does it travel in 2 s?

39.6 meters

10 meters

1 meter

3. If you throw an object downward at 10 ft/s, how far does it travel in 2 s?

8.4 feet

84 feet

840 feet

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.

It's fun to be able to figure things out
