Question

i can apply newton’s third law to design a solution to a problem involving the motion of two colliding objects. (ms-ps2-1)
key idea: newton’s third law: for every action, there is an equal and opposite reaction. forces always come in pairs.
practice question: in a game of pool, you use the pool stick to hit the white ball into another ball. the white ball slows and stops and the other ball starts rolling. why does the white ball stop and the other ball starts rolling?
your answer:
sally rolls a ball into object a; she then rolls the same ball into object b.
if not, review the understanding on newton’s 1st and 3rd laws of motion by doing the following:

• define energy transfer from one object to another, use your notes from hhe and force and motion.
• reflect on how balls on a pool table behave when someone exerts a force on the white ball.
• what happens after it hits another ball?
• newton’s 3rd law states that for every action there is an equal or greater reaction, when objects collide what happens to the object that is not moving when an object in motion hits it?

Explanation:

According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. When the white ball hits another ball (action), the other ball exerts an equal and opposite force on the white ball (reaction). This causes the white ball to slow down and stop (as the reaction force acts against its motion), while the other ball starts rolling (as the action force from the white ball acts on it). Also, energy transfer occurs (from the moving white ball to the initially stationary other ball), which is related to Newton's laws as the force application (a form of energy - transfer mechanism in this context of motion change) follows the third - law interaction.

Answer:

The white ball stops because the other ball exerts an equal and opposite force on it (Newton's Third Law), and the other ball starts rolling because the white ball exerts a force on it (also due to Newton's Third Law, and energy is transferred from the white ball to the other ball).
