Mini-Quiz: Equivalence Principles of Gravitation

by Ron Kurtus (revised 30 January 2018)

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

1. What is a requirement for the Weak Equivalence Principle?

Falling objects must be close to the mass of the Earth

The objects fall freely

The force of gravity must be very weak

2. If you double the acceleration of an object, how would that affect its inertia mass?

The acceleration has no effect on the mass of the object

The mass would double, since it is proportionate to the acceleration

The mass would become gravitational mass, provided a = g

3. What is an application of the Strong Equivalence Principle?

There are no applications, since it is just a theory

Time can be made to stand still

You can simulate gravity in a spaceship

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.

You can learn from performing experiments
