Newtons First Law

Front

What are the two factors that affect the amount of gravitational force between two objects?

Back

Mass and Distance.

Front

What is inertia?

Back

The tendency of an object to resist a change in motion.

Front

What happens to gravitational force as mass increases?

Back

It increases.

Front

What is the relationship between mass and gravitational force?

Back

Greater mass results in greater gravitational force.

Front

What type of force must act on an object in motion to change its state of motion?

Back

An unbalanced force.

Front

If an object is at rest, what can be said about the forces acting on it?

Back

The forces are balanced.

Front

What is an example of inertia in everyday life?

Back

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

Front

What does Newton's First Law state?

Back

An object in motion stays in motion unless acted upon by an unbalanced force.

Front

How does distance affect gravitational force?

Back

As distance increases, gravitational force decreases.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion; unbalanced forces do.
