What is net force?

Back

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

If you push a couch with 20 N to the right and your friend pushes with 25 N to the right, what is the net force?

Back

45 N to the right.

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is an example of balanced forces?

Back

Front

What is an example of unbalanced forces?

Back

What does Newton's 3rd Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

Give an example of Newton's 3rd Law of Motion.

Back

Two balls collide and bounce off of each other in opposite directions.

Front

What is the net force if two forces of 10 N and 5 N act in opposite directions?

Back

5 N in the direction of the larger force.

Front

What happens to an object when the net force is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is the formula to calculate net force?

Back

Net Force = Force1 + Force2 + ... + ForceN.
