How do you calculate net force?

Back

To calculate net force, add all the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

If Mr. Devers pushes a box 25 N to the right and then 30 N to the right, what is the net force?

Back

55 N unbalanced right.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

Front

What is an example of a force?

Back
