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 Friction?

Back

The force that opposes motion between two surfaces that are in contact with one another.

Front

What is Gravity?

Back

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

Front

What is a Balanced Force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an Unbalanced Force?

Back

Forces that are not equal, causing a change in motion of an object.

Front

How does surface texture affect friction?

Back

Rough surfaces create more friction, while smooth surfaces create less friction.

Front

Why do cars drive slower in the rain?

Back

The friction between tires and the road is decreased, making it harder to stop and control the vehicle.

Front

What is the relationship between force and motion?

Back

A force applied to an object can cause it to start moving, stop moving, or change direction.

Front

What is an example of a force?

Back

Pushing a door open or pulling a wagon.
