Give the consequences of Newton's second law of motion. (3 marks)
Newton;s Third Law of Motion states that Every action has an equal (in magnitude) and opposite (in direction) reaction.
The following are its consequences:
Cricket bowling: When the bowler bowls the ball to the batsman, the ball bounces with an intensity equal to the intensity at which the ball was thrown.
Swimming: The speed of the swimmer (in forward direction) is equal to the energy which he applies backward with his/her limbs.
Aircraft take-off or rocket launch : The engine propellers of the aircraft apply the force in the opposite direction to the desired direction of the force.
