Newton's Laws Assessment TSD

A person's body is forced back into their seat when an airplane suddenly accelerates during takeoff. Which law of motion does this demonstrate?

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Newton did not have cars in his time so he was not able to observe this kind of motion.

When rockets launch they use thrusters which apply a force against the ground. This force then pushes the rocket up into space. What law does this demonstrate?

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• All of the above

Which of the following formulas best represents Newton's 2nd Law of Motion?

• F=M/A

• F=M x d

• F=M/d

• F=M x A

Which of the following best represents inertia?

• When paddling a canoe, you push the oar backward and the canoe moves forward.

• A balloon playing around the room when the air is let out of it.

• A motorcycle requires less force to accelerate than a truck.

• Moving forward when your bicycle suddenly stops moving due to hitting a curb.

Which of the following is an example of Newton's 1st Law?

• Using a force to push grocery cart.

• Pulling back a rubber band to shoot it forward

• A chair remains motionless in a room

• None of the above

Which of the following is an example of Newton's 2nd Law?

• A basketball requires more force to roll than a tennis ball

• A picture hanging on the wall

• A rocket blasting off from the launch pad

• All of the above

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

• A child on a swing requires less force to move than an adult.

• Pushing water backward in order to move forward while swimming

• A pencil resting on a desk

• None of the above

Your neighbor has a lawn sprinkler that spins quickly as water shoots out of the top. Which principle best explains why the sprinkler spins?

• Objects in motion remain in motion unless acted upon by an unbalanced force.

• Objects at rest remain at rest unless acted upon by an unbalanced force.

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

• The force of an object is equal to its mass multiplied by its acceleration.

Newton's __ Law of motion states that an object at rest will remain at rest and an object in motion will remain in motion until acted upon by an unbalanced force.

Answer explanation

1st Law of Motion: Also known as the Law of Inertia, this law states that an object at rest will remain at rest and an object in motion will remain in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Newton's __​​ ​Law of motion states that the force of an object is equal to its mass multiplied by its acceleration.
