Newton's First Law

Front

What is Newton's First Law?

Back

Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is the law of inertia?

Back

The law of inertia is another name for Newton's First Law, which describes the tendency of objects to resist changes in their state of motion.

Front

What happens to an object if the forces acting on it are balanced?

Back

If the forces acting on an object are balanced, its motion will not change.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change its state of motion.

Front

What is a net force?

Back

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

Front

How do you calculate net force when two forces are acting in the same direction?

Back

To find the net force when two forces are acting in the same direction, you add the magnitudes of the two forces.

Front

What is inertia?

Back

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

Front

Can the law of inertia apply to nonmoving objects?

Back

Yes, the law of inertia applies to both moving and nonmoving objects.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when a person pushes a stationary car, causing it to move.

Front

What is the effect of a balanced force on a moving object?

Back

A balanced force on a moving object will keep it moving at a constant speed in a straight line.
