Front

What is the force that attracts any object with mass to another object with mass?

Back

Gravitational force.

Front

True or False: The gravitational pull is stronger when the masses of the objects are larger.

Back

True.

Front

What two factors determine the amount of gravitational force between two objects?

Back

Distance and mass.

Front

What is an example of a noncontact force?

Back

Gravity.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

Give an example of friction in action.

Back

A softball player sliding across the clay field to third base.

Front

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

Back

It decreases.

Front

What is the relationship between mass and gravitational pull?

Back

Greater mass results in a stronger gravitational pull.

Front

What is a noncontact force?

Back

A force that acts on an object without physical contact.

Front

What is the effect of gravity on objects in free fall?

Back

They accelerate towards the Earth at 9.8 m/s².
