Understanding Newton's Third Law of Motion

The video explains Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. It provides real-world examples, including a skateboarder performing a kickflip, a jet engine, paddling, a bouncing basketball, a jellyfish swimming, jumping on a trampoline, and a balloon hitting the earth. Each example illustrates how forces act in pairs, demonstrating the law's application in everyday scenarios.

What is the fundamental principle of Newton's Third Law of Motion?

• For every action, there is a similar reaction.

• For every action, there is an equal and opposite reaction.

• For every action, there is no reaction.

• For every action, there is a greater reaction.

In the context of a skateboarder, what must happen for the board to pop upward?

• The skateboarder must apply a force downward.

• The skateboarder must apply a force sideways.

• The skateboarder must pull the board upward.

• The skateboarder must push the board forward.

How does a jet engine demonstrate Newton's Third Law?

• The engine pushes air upward, moving the jet downward.

• The engine pushes air forward, moving the jet backward.

• The engine pushes air downward, moving the jet upward.

• The engine pushes air backward, moving the jet forward.

What action do the ladies perform to move their boat forward?

• They paddle upward.

• They paddle forward.

• They paddle backward.

• They paddle sideways.

Why does a basketball bounce upward after hitting the court?

• The ball exerts a downward force on the court.

• The ball loses energy and stops.

• The court exerts an upward force on the ball.

• The court absorbs the ball's energy.

How does a jellyfish move forward in water?

• By moving its body forward.

• By moving its body backward.

• By staying still.

• By moving its body upward.

What happens when a balloon hits the earth according to Newton's Third Law?

• It changes direction and goes upward.

• It stops moving.

• It continues moving downward.

• It moves sideways.
