Friction, Gravity, Mass and Force Review

Front

What is friction?

Back

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

Front

What factors affect the amount of friction between two surfaces?

Back

The amount of friction depends on the types of surfaces in contact and the force pressing them together.

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

How does mass affect the force of gravity?

Back

The greater the mass of an object, the stronger the gravitational pull it exerts.

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

What is mass?

Back

Mass is a measure of the amount of matter in an object, usually measured in kilograms.

Front

What is force?

Back

Force is a push or pull on an object that can cause it to accelerate, change direction, or change shape.

Front

What is air resistance?

Back

Air resistance is a type of friction that occurs when air pushes against a moving object, slowing it down.

Front

What type of surface would increase friction?

Back

A rough surface, such as rough paper, increases friction compared to a smooth surface.

Front

What is the effect of a smooth surface sloped downhill on a ball's motion?

Back

A smooth surface sloped downhill increases the motion of a ball after it is kicked.
