Quick comprehension check
“Two toy cars collide head-on. Car A exerts a force of 3 N on Car B. According to Newton's Third Law, what is the magnitude and direction of the force exerted by Car B on Car A? How could you change the mass of Car A to make it move less during the collision? A bicycle collides with a stationary box. The bicycle exerts a force of 10 N on the box. According to Newton's Third Law, what is the magnitude and direction of the force exerted by the box on the bicycle? How could you change the mass of the box to make it move more during the collision? A ball is dropped and hits the floor. The ball exerts a force of 5 N on the floor. According to Newton's Third Law, what is the magnitude and direction of the force exerted by the floor on the ball? How could you change the mass of the ball to make it move less after the collision?”
