Gravity, Mass, and Weight

Front

What is gravity?

Back

A force that attracts two bodies towards each other.

Front

What is mass?

Back

The amount of matter in an object, measured in kilograms.

Front

What is weight?

Back

The force of gravity acting on an object, calculated as mass times the acceleration due to gravity.

Front

Does weight change on different planets?

Back

Yes, weight changes depending on the gravitational pull of the planet.

Front

If Earth's mass was cut in half, what happens to your mass?

Back

Nothing, mass is not affected by gravitational force.

Front

How does distance affect the pull of gravity?

Back

As distance between two objects increases, the pull of gravity decreases.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; more mass means more weight.

Front

What unit is weight measured in?

Back

Weight is measured in newtons (N).

Front

What unit is mass measured in?

Back

Mass is measured in kilograms (kg).

Front

What happens to your weight if you go to the Moon?

Back

Your weight decreases because the Moon has less gravitational pull than Earth.
