Gravitational force is the attraction between two objects due to their mass.

Front

How does mass affect gravitational pull?

Back

The more mass an object has, the stronger its gravitational pull.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is a noncontact force?

Back

A noncontact force is a force that can act on an object without physical contact, such as gravitational or magnetic force.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion between magnets.

Front

What is an example of a contact force?

Back

Friction is an example of a contact force.

Front

How can forces affect the motion of an object?

Back

Forces can change an object's speed and direction.
