Newton's Laws Quiz

What is Newton's First Law of Motion also known as?

• Law of Inertia

• Principle of Motion

• Newton's Third Law

• Law of Rest

According to Newton's First Law, an object at rest will remain at rest unless acted upon by what?

• stationary force

• internal force

• external force

• inertia force

In Newton's First Law, what is the term used to describe an object's resistance to change in motion?

• momentum

• inertia

• acceleration

• velocity

True or False: Newton's First Law states that an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

• False

• Objects in motion stop immediately

• An object in motion will speed up

• True

What is the other name for Newton's First Law?

• Law of Inertia

• Newton's Third Law

• Principle of Equilibrium

• Law of Rest

According to Newton's First Law, what happens to an object in motion if no external force is applied to it?

• It will continue to move at a constant velocity in a straight line.

• It will change direction randomly.

• It will slow down and eventually stop.

• It will speed up indefinitely.

What is the key concept behind Newton's First Law of Motion?

• Friction

• Gravity

• Inertia

• Acceleration

What is the formula for Newton's First Law of Motion?

• ΣF = ma

• F = mv^2

• F = ma

• F = 0 or ΣF = 0

What is the significance of Newton's First Law in understanding the behavior of objects?

• Objects can change direction without any external force

• Newton's First Law helps us understand that objects tend to maintain their state of motion unless acted upon by an external force.

• Objects stop moving immediately when no force is applied

• Objects always accelerate when in motion

How does Newton's First Law relate to the concept of inertia?

• Newton's First Law states that objects will stop moving if no force is applied.

• Newton's First Law relates to the concept of inertia by explaining that objects will maintain their current state of motion (or lack of motion) unless an external force is applied to change it.

• Objects in motion will slow down due to inertia according to Newton's First Law.

• Inertia is the force that causes objects to accelerate.
