#5 Calculating Net Forces (Flashcard Grade)

Front

What is the standard unit of force?

Back

Newton (N)

Front

How do you calculate net force?

Back

By adding all the forces acting on an object.

Front

What does a net force of 0 N indicate about an object's motion?

Back

The object is either at rest or moving at a constant velocity.

Front

If two forces are acting in the same direction, how do you find the net force?

Back

Add the magnitudes of the forces together.

Front

What is the net force when one force of 200 N east and another of 150 N east are applied?

Back

350 N east.

Front

What is Newton's First Law of Motion also known as?

Back

The Law of Inertia.

Front

What does Newton's First Law state about an object at rest?

Back

An object at rest will stay at rest unless acted upon by a net external force.

Front

What does Newton's First Law state about an object in motion?

Back

An object in motion will continue in motion at a constant velocity unless acted upon by a net external force.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the object's motion.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause a change in the object's motion.
