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

by Ron Kurtus (revised 7 February 2011)

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

1. If you double the initial velocity, how does that affect the maximum displacement?

It is 4 times as great

It is doubled

It is cut in half

2. If the initial velocity is −10 ft/s, how far will the object travel in 1 second?

10 ft

6 ft

1 ft

3. If the maximum displacement is −20 m, what is |2ym|?

− 40 m

It cannot be calculated

40 m

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.
