Newton's Laws of Motion Quiz

What does Newton's First Law of Motion state about an object at rest?

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

• It will increase its speed.

• It will start moving on its own.

• It will change its direction.

How is inertia related to mass?

• Inertia is inversely proportional to mass.

• Inertia is not related to mass.

• Inertia is directly proportional to mass.

• Inertia is equal to mass.

According to Newton's Second Law, what happens to acceleration if the force applied to an object is increased?

• Acceleration becomes zero.

• Acceleration decreases.

• Acceleration remains the same.

• Acceleration increases.

What is the relationship between mass and acceleration according to Newton's Second Law?

• They are not related.

• They are inversely proportional.

• They are equal.

• They are directly proportional.

Newton's Third Law is often summarized as:

• For every action, there is a similar reaction.

• For every action, there is no reaction.

• For every action, there is a greater reaction.

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

In an action-reaction pair, how do the forces compare?

• They are equal in magnitude and opposite in direction.

• They are equal in magnitude and direction.

• They are different in magnitude and direction.

• They are different in magnitude but same in direction.

When drawing action-reaction pairs, where should the forces be applied?

• On the same object.

• On the larger object.

• On different objects.

• On the ground.

What happens when a boy pushes against the ground while running?

• The ground moves.

• The boy falls.

• The boy remains stationary.

• The ground pushes back with an equal force.

What is the main focus of Newton's Third Law?

• Unbalanced forces.

• Balanced forces.

• Action-reaction force pairs.

• Constant velocity.
