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 speed?

Back

The distance an object travels in a certain amount of time.

Front

What is gravity?

Back

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

Front

What is friction?

Back

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

Front

How can you increase the speed of an object?

Back

By applying more force to it.

Front

What happens to an object's speed when it goes down a ramp?

Back

The object usually speeds up due to gravity.

Front

What is the relationship between distance and speed?

Back

If you travel a longer distance in the same amount of time, your speed is higher.

Front

What is the effect of mass on force?

Back

Heavier objects require more force to move than lighter objects.

Front

What is a simple way to decrease speed?

Back

Increase friction or apply a force in the opposite direction.

Front

What does it mean to travel at a faster rate of speed?

Back

It means covering more distance in the same amount of time compared to another object.
