Newton's Laws and Graphing

Forces that are equal in size but opposite in direction are

• balanced forces

• net forces

• frictional forces

• inertial forces

A friend is helping you move a cart. You exert 25N of force to push on the back of the cart while your friend exerts 20N of force pulling on the front of the cart. The net force being used to move the cart is

• 20N Forward

• 25N Forward

• 5N Forward

• 45N Forward

Balanced forces acting on an object

• sometimes change the object's motion

• never change the object's motion

• always change the object's motion

• are not related to motion
