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 examples such as rocket propulsion, jumping, and swimming to illustrate the concept. The video concludes by encouraging viewers to explore more about Newton's laws on the GCF Global website.

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

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

• An object in motion stays in motion.

• Energy cannot be created or destroyed.

• Force equals mass times acceleration.

How do rockets utilize Newton's Third Law to travel into space?

• By using solar energy to lift off.

• By expelling gas upwards to create lift.

• By expelling gas downwards to generate thrust.

• By reducing their mass to increase speed.

What is the reaction force when a rocket expels gas downwards?

• The rocket moves sideways.

• The rocket experiences an upward force.

• The rocket remains stationary.

• The rocket moves downwards.

What happens when a person jumps according to Newton's Third Law?

• The ground absorbs all the force.

• The ground exerts an equal and opposite force upwards.

• The person floats due to reduced gravity.

• The person remains stationary.

What is the result of using minimal force when jumping?

• A lower jump.

• A higher jump.

• A jump with the same height.

• No jump at all.

What is the action when Joan jumps into the air?

• Her arms swing upwards.

• Her body remains still.

• Her head tilts back.

• Her feet push the ground.

What is the reaction when Joan pushes the ground with her legs?

• The ground absorbs the force.

• The ground pushes her upward.

• The ground moves sideways.

• The ground remains unaffected.

In the context of swimming, how does exerting more force affect movement?

• It has no effect on the swimmer's speed.

• It propels the swimmer faster and further.

• It causes the swimmer to sink.

• It slows down the swimmer.

What is the effect of a leisurely stroke in swimming?

• It has no effect on the swimmer's movement.

• It makes the swimmer sink.

• It causes the swimmer to travel a short distance.

• It propels the swimmer quickly.

Where can you learn more about Newton's laws?

• In a physics textbook.

• On the GCF Global website.

• At the local library.

• By watching a documentary.
