Gravity Review

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What factors affect the strength of gravity between two objects?

Back

The strength of gravity is affected by the masses of the objects and the distance between them.

Front

When will the forces of gravity between two objects be the GREATEST?

Back

When the masses of both objects are large and the objects are close together.

Front

What is the SI unit used to measure force?

Back

The SI unit used to measure force is newtons.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

Why can astronauts jump and float a little on the Moon?

Back

Because the Moon's gravity is NOT that STRONG.

Front

What happens to the force of gravity as the distance between two objects increases?

Back

The force of gravity decreases as the distance between two objects increases.

Front

If two objects have the same mass, how does distance affect their gravitational attraction?

Back

The gravitational attraction decreases as the distance between the two objects increases.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force of the medium through which it is falling.

Front

What would happen if the Earth had no gravity?

Back

If the Earth had no gravity, objects would not be pulled towards the ground, and everything would float away.
