Mini-Quiz: Overview of Gravity Equation Derivations

by Ron Kurtus (revised 7 January 2011)

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

1. What is the primary assumption in deriving the gravity equations?

Calculus is similar to algebra, only harder

Force is F = ma

The acceleration due to gravity is a constant value

2. Why is displacement used in the equations instead of distance?

Displacement is in a specific direction, while distance is independent of direction

Either displacement or direction can be used

Neither is ever used in the time equations

3. What is the displacement from the starting point when v = vi?

It is impossible for v to equal vi



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.
