What is an action-reaction pair of forces?

• An action-reaction pair of forces is a pair of forces that are equal in magnitude and same in direction.

• An action-reaction pair of forces is a pair of forces that are unequal in magnitude and opposite in direction.

• An action-reaction pair of forces is a pair of forces that are equal in magnitude and opposite in direction.

• An action-reaction pair of forces is a pair of forces that are equal in magnitude and different in direction.

• Because they are both pulling the same amount of force in opposite directions
• Because they are elephants
• Because they are pulling away from each other.
