Newton's Laws of Motion Quiz

What is the primary difference between contact forces and field forces?

• Contact forces require physical contact, while field forces do not.

• Field forces require physical contact, while contact forces do not.

• Both require physical contact.

• Neither requires physical contact.

Which of the following is the strongest of the four fundamental forces?

• Gravity

• Electromagnetic force

• Weak nuclear force

• Strong nuclear force

What is the weakest of the four fundamental forces?

• Strong nuclear force

• Electromagnetic force

• Weak nuclear force

• Gravity

According to Newton's First Law, what happens to an object if no net force acts on it?

• It will come to a stop.

• It will accelerate.

• Its velocity will remain constant.

• It will change direction.

What does Newton's First Law of Motion also refer to?

• Law of Gravity

• Law of Acceleration

• Law of Action and Reaction

• Law of Inertia

How is force mathematically represented in Newton's Second Law?

• Force = Mass + Acceleration

• Force = Mass - Acceleration

• Force = Mass / Acceleration

• Force = Mass x Acceleration

In Newton's Second Law, if the mass of an object is doubled, what happens to the acceleration if the force remains constant?

• Acceleration doubles.

• Acceleration halves.

• Acceleration remains the same.

• Acceleration becomes zero.

What is the SI unit of force?

• Newton

• Joule

• Pascal

• Watt

Newton's Third Law states that for every action, there is:

• A lesser reaction.

• An equal and opposite reaction.

• No reaction.

• A greater reaction.

If you push against a wall, what does Newton's Third Law imply?

• The wall pushes back with equal force.

• The wall does not push back.

• The wall pushes back with more force.

• The wall pushes back with less force.
