Force & Motion Review

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is mass?

Back

The amount of matter in an object, usually measured in grams or kilograms.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is friction?

Back

A force that opposes motion between two surfaces that are in contact.

Front

What is acceleration?

Back

The rate at which an object changes its velocity, which can be an increase or decrease in speed.

Front

What is a control in an experiment?

Back

The part of the experiment that remains constant and is used for comparison.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to move it.

Front

What happens when you push an object with greater force?

Back

The object will accelerate more and move faster.

Front

What is the effect of surface material on friction?

Back

Different materials create different amounts of friction; rough surfaces create more friction than smooth surfaces.
