Force and Motion #5A

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

How does mass affect motion?

Back

More mass means more force is needed to change its motion.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

How can you increase the speed of an object?

Back

By applying a greater force or reducing its mass.

Front

What happens when you decrease the mass of an object?

Back

It requires less force to accelerate and can move faster.

Front

What is the relationship between force and acceleration?

Back

Greater force results in greater acceleration, according to Newton's second law.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force.

Front

What is the effect of adding weight to a moving object?

Back

It can slow down the object because it increases the mass.

Front

What is the best way to make a ball roll farther?

Back

Reduce its mass or decrease friction.
