Force and Net Force Review

Net Force review

As a review- Net force is the combination of forces on an object.​

Answer will need the netforce (in Newtons) and the direction

Net Force

Multiple Choice

What is Force?

• A pull exerted on an object

• A push exerted on an object

• A push or pull exerted on an object

• Nothing

Multiple Choice

What is the unit for FORCE? 

• N (Newtons)

• lbs (pounds)

• g (grams)

• m/s (meters per second)

As a Review:

• If the forces are going in the same direction: you add the forces

• If the directions are going in different directions: you subtract the forces

• If there is a combination: add the ones that are the same, then subtract the different directions.
