Newton's 3rd Law

The video explains Newton's 3rd Law of Motion, which states that for every action, there is an equal and opposite reaction. It provides examples from nature, such as fish swimming and birds flying, and everyday scenarios like running and surfing. The video encourages viewers to reflect on their own experiences with action-reaction force pairs.

What does Newton's 3rd Law of Motion state?

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

• An object in motion stays in motion unless acted upon by an external force.

• Force equals mass times acceleration.

• Energy cannot be created or destroyed.

Which of the following is an example of Newton's 3rd Law in nature?

• A river flowing downstream.

• A car accelerating on a highway.

• A fish using its fins to move forward.

• A tree growing towards sunlight.

When a ball bounces on the ground, what is the reaction force?

• The ball's spin affecting its trajectory.

• The air resistance slowing the ball.

• The ground pushing the ball upwards.

• The ball's weight pulling it down.

What role does friction play when you run on a surface?

• It only affects your speed, not direction.

• It has no effect on your movement.

• It slows you down by opposing your motion.

• It helps you move forward by pushing back against your foot.

Why is it difficult to walk on a slippery surface like ice?

• Because there is too much friction.

• Because the surface is too soft.

• Because there is not enough friction.

• Because the surface is too hard.
