Newton's Laws and Balanced Forces

When two equal forces act in opposite directions on an object, they are called ______________________.

• frictional force

• balanced force

• centripetal force

• gravitational force

When an unbalanced force acts on an object, the force ______________________.

• changes the motion of the object

• is cancelled by another force

• does not change the motion of an object

• is equal to the weight of the object
