Mini-Quiz: General Relativity Theory of Gravitation

by Ron Kurtus

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

1. What is spacetime?

The combination of the three dimensions of space with time

The time is takes an object to travel in space


2. Why would the planet Mercury have an unusual orbit?

Mercury is in the realm of spacetime, thus causing relativity from the Sun

Mercury is a shiny liquid planet, thus affecting its motion

It is so close to the Sun that the high gravitational field affects its motion differently than planets further away from the Sun

3. What is one difficulty with the General Relativity explanation?

Gravitation doesn't fit with other fundamental forces

No one, except Einstein, can understand it

Space is empty, so it cannot be curved

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 measure relative to a standard
