Force and Motion - Ch. 1 & 2

Front

What is force?

Back

A push or pull that can cause motion.

Front

What direction must a force be applied to start an object moving?

Back

Any direction.

Front

What is the net force?

Back

The overall force acting on an object after all the forces are combined.

Front

If two forces are acting in opposite directions, how do you find the net force?

Back

Subtract the smaller force from the larger force.

Front

What is velocity?

Back

The speed of an object in a specific direction.

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

What is mass?

Back

The amount of matter in an object.

Front

How does mass affect force?

Back

More mass requires more force to achieve the same acceleration.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

What happens to an object at rest when a force is applied?

Back

It may start to move if the force is strong enough.
