physical science review

What is the definition of a force?

• Net force equal 0N and there is no change in the object's motion

• the overall force acting on an object after all forces are combined

• a push or a pull that acts on an object

• The force does not equal 0N, the object accelerates

What do we call a force that has a net force of zero Newtons and the object does not change its motion?

• balanced force

• unbalanced force

• acceleration force

• net force

What is the magnitude and direction of the force in the free body diagram shown?

• 70 N right

• 70 N left

• 50 N right

• 50 N left
