Newton's First Law - Review

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 an unbalanced force.

Front

What does inertia mean?

Back

Inertia is the tendency of an object to resist a change in its state of motion.

Why does a car fall off a truck bed when the truck stops suddenly?

Back

Because the car wants to stay at rest due to inertia.

Front

What happens to a resting object according to Newton's First Law?

Front

What is the relationship between mass and inertia?

Back

Objects with greater mass have greater inertia.

Give an example of inertia in everyday life.

Back

A passenger lurches forward in a car when it suddenly stops.

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes motion, which can slow down or stop moving objects.

Front

How does mass affect the force needed to change an object's motion?

Back

More mass means more force is required to change the object's motion.
