Force. Gravity, Friction

Front

What is a non-contact force?

Back

A force that does not require physical contact between objects, such as gravity.

Front

What is weight?

Back

The measure of the force of gravity acting on an object.

Front

What two factors affect gravity?

Back

Mass and distance.

Front

What happens to gravitational force if the distance between two objects is doubled?

Back

It becomes four times weaker.

Front

What would happen without gravity?

Back

We would float away.

Front

What is gravity?

Back

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

Front

What is friction?

Back

A force that opposes the motion of an object when it comes into contact with another surface.

Front

What is the normal force?

Back

The support force exerted upon an object that is in contact with another stable object.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational pull.

Front

What is the relationship between distance and gravitational force?

Back

As distance increases, gravitational force decreases.
