• 140 N

• 25 N

• 30 N

How would you calculate the net force acting on the box in the diagram?

• Find the difference between the forces because they are acting in different directions

• Find the difference between the forces because they are acting in the same direction

• Find the sum of the forces because they are acting in different directions

True or False? If the action force of a bowling ball hitting a pin accelerates the pin in one direction, the reaction force accelerates the bowling ball in the opposite direction.

• True

• False

What is the equation that describes the relationship between force, mass and acceleration?

• Force = acceleration / mass

• Force = mass / acceleration

• Force = momentum + acceleration

• Force = mass x acceleration
