by Ron Kurtus

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

1. What is a major concept of gravity?

Gravity equations are based on the weight of an object

The acceleration due to gravity is constant close to Earth

Objects must be made of some metal to be affected by gravity

2. Which is the correct theory of gravitation?

Dark gravitation is the only true theory

Gravity

They all apply in certain situations

3. What is the use of gravity and gravitation equations?
