Front

What is speed?

The distance traveled by an object in a given amount of time.

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

What happens when two forces act in the same direction?

Back

The forces add together to create a larger force.

Front

What happens when two forces act in opposite directions?

Back

The forces subtract from each other, resulting in a net force.

Front

What is friction?

Back

A force that opposes the motion of an object.

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 inertia?

Back

The tendency of an object to resist changes in its state of motion.
