Newton's First Law

Front

Because of inertia, a resting object will remain at ________.

Back

rest

Front

Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until a _________ acts on them.

Back

force

Front

If a hockey puck slides on a frictionless surface, it will eventually slow down because of its inertia. True or False?

Back

False

Front

An object following a straight-line path at a constant speed has _________.

Back

zero acceleration

Front

An object in motion tends to stay in motion unless an ___ force acts on it.

Back

unbalanced

Front

What is inertia?

Back

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

Front

What does Newton's First Law state?

Back

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

Front

Give an example of an object in motion that continues moving in a straight line.

Back

A hockey puck sliding on ice.

Front

What happens to a moving object when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is a net force?

Back

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