5.P.1.1 Force & Motion

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 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 the motion of an object, caused by the contact between two surfaces.

Front

What is mass?

Back

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

Front

How does increasing mass affect force needed to move an object?

Back

Increasing the mass of an object requires more force to start moving it.

Front

What happens to the speed of an object when a force acts in the direction of its motion?

Back

The speed of the object increases.

Front

What is momentum?

Back

The quantity of motion an object has, which depends on its mass and velocity.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, an increase in mass results in a decrease in acceleration if the same force is applied.

Front

What is an example of an object in motion?

Back

A car driving down the road.
