Question

how does newtons third law of motion explain why when you throw a bouncy ball at the floor, it bounces back up? (1 point)
the kinetic energy of the ball turns into potential energy when it hits the floor.
the ball is pushed away from the floor by the electromagnetic repulsion of the atoms that make up the floor.
the acceleration of the ball when it bounces is reversed to its opposite as it rises back up.
from the force of the ball on the floor, there is an equal and opposite reaction of the force of the floor on the ball.

Explanation:

Newton's third law states that for every action, there is an equal and opposite reaction. When the ball exerts a force on the floor (action), the floor exerts an equal and opposite force on the ball (reaction), causing it to bounce back.

• The first option is about energy conversion (kinetic to potential) which is related to conservation of energy, not Newton's third law.
• The second option is about electromagnetic repulsion of atoms, not directly related to Newton's third law as stated in the question context.
• The third option is about acceleration reversal, which is more related to kinematics (motion equations) rather than the force - pair concept of Newton's third law.

Answer:

From the force of the ball on the floor, there is an equal and opposite reaction of the force of the floor on the ball.
