Newton's First Law of Motion Quiz

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

• Law of Gravity

• Law of Inertia

• Law of Acceleration

• Law of Energy

According to Newton's First Law, what happens to an object at rest?

• It starts moving on its own

• It remains at rest unless acted on by an unbalanced force

• It disappears

• It changes direction

What is required to stop an object in motion according to Newton's First Law?

• Gravity

• An unbalanced force

• Friction

• Air resistance

Why is it harder to move a wagon of bricks compared to a wagon of leaves?

• Bricks have less inertia

• Bricks have greater mass and therefore more inertia

• Leaves are heavier than bricks

• Leaves have more inertia

What does inertia mean in Newton's First Law of Motion?

• An object will change its state automatically

• An object will keep doing what it’s been doing unless acted upon by an unbalanced force

• An object will always stay at rest

• An object will always stay in motion

What is friction and how does it affect a moving object?

• A force that speeds up the movement of objects.

• A force that resists the movement of one surface against another.

• A force that pulls objects downward.

• A force that makes objects float in the air.

What happens to a soccer ball rolling downhill due to gravity?

• It slows down and stops.

• It moves uphill instead of downhill.

• It speeds up as it moves downhill.

• It stays at a constant speed.

What is air resistance and how does it affect a moving object?

• A force that speeds up objects in the air.

• A force that resists the motion of objects moving through the air.

• A force that pulls objects downward.

• A force that makes objects move in circles.

What would happen to a baseball in space where there is no friction or gravity?

• It would stop moving immediately.

• It would move in circles.

• It would keep moving in the same direction at the same speed.

• It would fall back to Earth.

What is acceleration in terms of motion?

• A force that resists motion.

• A change in speed or direction of an object.

• A force that pulls objects downward.

• A state where an object remains stationary.
