TAS lets explore NEWTON's THIRD LAW

What is Newton's Third Law of Motion?

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

• An object at rest stays at rest unless acted upon by an external force.

• The acceleration of an object is directly proportional to the net force acting on it.

• Energy cannot be created or destroyed.

In a game of soccer, when a player kicks the ball, how does Newton's Third Law apply?

• The ball exerts an equal and opposite force on the player's foot.

• The ball moves in the direction of the kick.

• The player's foot stops moving.

• The ball accelerates due to gravity.

How can Newton's Third Law be applied to improve performance in sports like basketball?

• By increasing the force applied when jumping, the reaction force from the ground will be greater, allowing higher jumps.

• By reducing the mass of the basketball, it will travel faster.

• By using a lighter shoe, the player can run faster.

• By practicing more, the player becomes more skilled.

A car crashes into a wall. According to Newton's Third Law, what happens to the forces involved?

• The car exerts a force on the wall, and the wall exerts an equal and opposite force on the car.

• The car exerts a force on the wall, but the wall does not exert any force.

• The wall exerts a force on the car, but the car does not exert any force.

• The forces cancel each other out, resulting in no damage.

• Drop a ball and observe its bounce.

• Push two identical carts towards each other and observe their motion upon collision.

• Roll a ball down a ramp and measure its speed.

• Spin a top and observe its motion.

Explain how Newton's Third Law is applied in the motion of a skateboarder pushing off the ground.

• The skateboarder exerts a force on the ground, and the ground exerts an equal and opposite force on the skateboarder, propelling them forward.

• The skateboarder moves forward due to gravity.

• The skateboarder moves forward because of friction.

• The skateboarder moves forward due to air resistance.

Analyze the forces involved when a baseball player hits a ball with a bat. How does Newton's Third Law apply?

• The bat exerts a force on the ball, and the ball exerts an equal and opposite force on the bat, affecting the player's grip.

• The bat exerts a force on the ball, and the ball moves in the direction of the hit.

• The ball exerts a force on the bat, and the bat moves backward.

• The bat exerts a force on the ball, and the ball exerts no force on the bat.

Evaluate the role of Newton's Third Law in the design of safety features in cars, such as airbags.

• Airbags provide a cushion that exerts an equal and opposite force to the force of the passenger moving forward, reducing injury.

• Airbags stop the passenger from moving forward.

• Airbags increase the force on the passenger to stop them quickly.

• Airbags do not relate to Newton's Third Law.
