Newton's Laws Quiz

According to Newton's second law of motion, what is the relationship between force, mass, and acceleration?

• force = mass - acceleration

• force = mass * acceleration

• force = mass / acceleration

• force = mass + acceleration

What is inertia?

• The tendency to move in a straight line

• The force that causes objects to fall towards the Earth

• The ability to change direction easily

• Resistance to changes in motion or rest.

What is the formula to calculate force?

• force = mass / acceleration

• force = mass + acceleration

• force = mass - acceleration

• force = mass * acceleration

What is the third law of motion?

• Every action has an equal and opposite reaction.

• For every action, there is no reaction.

• For every action, there is a smaller reaction.

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

What is the unit of force?

• Second

• Meter

• Newton

• Kilogram

What is the action-reaction pair in the following scenario: A person pushes a wall.

• The person pushing on the wall and the wall pulling the person towards it.

• The person pushing on the wall and the wall moving away from the person.

• The person pushing on the wall and the wall disappearing.

• The person pushing on the wall and the wall pushing back on the person.

What is the action-reaction pair in the following scenario: A car accelerates forward.

• The car pushing forward on the ground and the ground pushing backward on the car.

• The car pushing backward on the ground and the ground pushing forward on the car.

• The car pushing forward on the air and the air pushing backward on the car.

• The car pushing backward on the air and the air pushing forward on the car.

What is the action-reaction pair in the following scenario: A ball bounces off a wall.

• The ball exerting a force on the wall and the wall exerting an equal and opposite force on the ball.

• The ball exerting a force on itself and the wall exerting an equal and opposite force on itself.

• The ball exerting a force on the air and the air exerting an equal and opposite force on the ball.

• The ball exerting a force on the ground and the ground exerting an equal and opposite force on the ball.

What is the action-reaction pair in the following scenario: A rocket launches into space.

• The rocket pushing against the air molecules in the atmosphere and the air molecules pushing back against the rocket.

• The rocket pushing against the vacuum of space and the vacuum of space pushing back against the rocket.

• The rocket pushing against the gases expelled from its engines and the gases pushing back against the rocket.

• The rocket pushing against the Earth's gravity and the Earth pushing back against the rocket.
