Back

opposite

Back

action and reaction

8 N to the left , and 4 N to the right. Find the net force. Is this balanced 

Back

4 N Left  No

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 a net external force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating net force?

Back

Net Force = Force applied - Force opposing

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in motion (acceleration) of an object.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

F = ma (Force equals mass times acceleration).
