Newton's Second Law Quiz

Michael is pushing a box with a certain force and it accelerates. Noah and Arjun are observing this. According to Newton's second law of motion, how would you express the force Michael is applying on the box?

• F = ma^2

• F = m/a

• F = ma

• F = mv

Aiden and Sophia are conducting a physics experiment. They observe that when they double the force applied to a cart, what happens to its acceleration according to Newton's second law?

• The acceleration of the cart will remain the same.

• The acceleration of the cart will quadruple.

• The acceleration of the cart will halve.

• The acceleration of the cart will double.

Oliver and Rohan are in a physics class. Their teacher, Priya, asks them to identify the SI unit of force that is used when they push or pull an object. What is the correct unit?

• Newton (N)

• Second (s)

• Meter (m)

• Kilogram (kg)

Abigail is conducting a physics experiment. She has an object with a mass of 5 kg. If William applies an acceleration of 2 m/s^2 to the object, what is the force that William is applying on the object?

• 10 N

• 2 N

• 7 N

• 15 N

Sophia is studying physics and she comes across a problem where she needs to understand the relationship between the force applied by Benjamin on a football and the resulting acceleration of the football. According to Newton's second law, what is this relationship?

• Force and acceleration are inversely proportional according to Newton's second law.

• Force and acceleration are not related according to Newton's second law.

• Force and acceleration are equal according to Newton's second law.

• Force and acceleration are directly proportional according to Newton's second law.

Zoe, Noah, and Benjamin were discussing physics. Zoe said that when she pushes her bicycle, it continues to move even when she stops pushing. Noah said that this is due to a property of matter. What is this property that Noah is referring to?

• The ability of the bicycle to move without any external force.

• The force that causes the bicycle to move in a circular path.

• The resistance of the bicycle to changes in its shape or size.

• Resistance of the bicycle to changes in its motion or rest.

Ethan, Benjamin, and Ava are observing a soccer ball on a field. If the net force acting on the soccer ball is zero, what can they say about its motion?

• The soccer ball is changing direction frequently.

• The soccer ball is either at rest or moving at a constant velocity.

• The soccer ball is moving in a circular path.

• The soccer ball is accelerating.

Abigail and Aiden are playing a game where Aiden pushes a wall. What is the action-reaction pair in this scenario?

• The wall pushes Aiden back with a greater force.

• The wall moves in the opposite direction.

• The wall absorbs the force and does not react.

• Aiden exerts a force on the wall and the wall exerts an equal and opposite force on him.

Liam, Isla, and Noah are trying to balance a seesaw. If the seesaw is perfectly balanced and not moving, what is the net force acting on the seesaw?

• Negative

• Zero

• Positive

• Undefined

William is conducting an experiment. He has an object and he doubles its mass. What happens to the object's inertia?

• The inertia of the object will decrease by half.

• The inertia of the object will double.

• The inertia of the object will remain the same.

• The inertia of the object will halve.
