Mini-Quiz: Strong Equivalence Principle of Gravitation

by Ron Kurtus (updated 30 May 2023)

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



1. What is a limitation in showing this principle in a spaceship?

Experiments are limited by the astronaut's space suit

Acceration is limited by the speed of light

It has never been tried before

2. What conclusion did Einstein made about gravitation?

Gravitation is geometrical in nature

Gravitation does not exist in space

Gravitation requires fast-moving objects

3. What comes into effect when the mass is equal to the attracting object?

The weak principle does not hold since they both move toward their center of mass

The velocity is doubled

The objects still fall at the same rate no matter what their masses are

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
