Front

What is friction?

Back

A contact force that opposes the motion of an object, acting in the opposite direction of the object's movement.

Front

What is gravitational force?

Back

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

Front

What is normal force?

Back

The support force exerted by a surface perpendicular to the object resting on it.

Front

How does distance affect gravitational force?

Back

As objects move away from each other, the gravitational force between them decreases.

Front

How does mass affect gravitational force?

Back

As the mass of two objects increases, the gravitational force between them increases.
