Which of Newton's Laws of Motion explains the principle of action and reaction?

• First Law

• Second Law

• Third Law

• Fourth Law

Which of Newton's Laws states that an object at rest will stay at rest unless acted upon by an unbalanced force?

• 1st Law

• 2nd Law

• 3rd Law

• Law of Gravity

According to Newton's 2nd Law, what is the relationship between force, mass, and acceleration?

• Force equals mass times velocity

• Force equals mass times acceleration

• Force equals mass divided by acceleration

• Force equals acceleration divided by mass

What does Newton's 3rd Law of Motion state?

• An object in motion stays in motion

• Force equals mass times acceleration

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

• An object at rest stays at rest

What does the 1st Law of Motion, also known as the Law of Inertia, state about an object at rest?

• It will start moving on its own.

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

• It will change direction.

• It will increase in speed.

What is inertia?

• The tendency of an object to resist changes in its velocity

• The force that causes objects to move

• The speed at which an object travels

• The energy required to stop an object

What happens to an object once it is airborne if no unbalanced force acts on it?

• It will eventually stop on its own.

• It will continue moving indefinitely.

• It will change direction randomly.

• It will slow down gradually.

What does the 1st Law of Motion state about an object at rest, like a golf ball on a tee?

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

• It will start moving on its own after some time.

• It will remain at rest only if the temperature is constant.

• It will move if the air pressure changes.

Why do objects on Earth experience friction, unlike the moon in space?

• Because Earth has an atmosphere

• Because Earth is larger than the moon

• Because Earth is closer to the sun

• Because Earth has gravity

What is the unbalanced force that acts on an object in motion?

• Gravity

• Friction

• Magnetism

• Inertia
