Look at this image. Why wouldn't acceleration be equal according to Newton's third law?

• The cars are moving in different directions.

• The cars are moving in the same direction.

• The cars have different masses.

• The cars have balanced forces.

When the car collides with the wall, what must be true?

• The acceleration must be equal.

• Both must exert the same force.

• The wall must exert a greater force.

• The wall and car accelerate in opposite directions.

Which scenario best demonstrates Newton's third law?

• A person jumping off a boat.
• A person sitting on a chair.
• A balloon rising in the air.
• A car accelerating on a highway.

Three marbles if varying masses are all released down the same ramp. Which law describes why the heavier marble accelerates faster?

• First Law

• Second Law

• Third Law

When launching rockets, Mara notices that her rocket with more fins doesn't accerlate as quickly as her partner's rocket with fewer fins. How does one of Newton's Law shelp explain this?

• According to Newton's second law, The rocket with more fins has increased mass, reducing its acceleration.

• According to Newton's second law, Both rockets should accelerate at the same rate regardless of fin count.

• According to Newton's first law, The rocket with fewer fins has more mass, slowing it down.

• According to Newton's first law, more fins increase thrust, leading to faster acceleration.

Imagine a car traveling in a straight line when another car crashes into it from behind. The moving car applies a force on the car that was at rest, causing it to speed up. At the same time, the car that was at rest exerts an equal and opposite force on the moving car. This results in the moving car slowing down or changing direction. Which of Newton's Laws does this situation illustrate?

• First Law

• Second Law

• Third Law

Imagine a soccer ball rolling across a field. Over time, it slows down and eventually stops. Which of Newton's three laws does the example illustrate?

• First Law

• Second Law

• Third Law
