Laws of Motion Quiz for 5th Grade

What does Newton's First Law of Motion state?

• Objects in motion stay in motion unless acted upon by an outside force.

• The acceleration of an object depends on its mass and the force applied to it.

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

• Gravity is the force that attracts two bodies toward each other.

If you push an empty shopping cart and a full one with the same force, which one will accelerate more?

• The empty shopping cart

• The full shopping cart

• Both will accelerate the same

• Neither, they will not move

What does Newton's Second Law of Motion state?

Which of the following is an example of friction?

• A ball rolling down a hill

• A magnet sticking to a fridge

• Rubbing your hands together to warm them

• Jumping high into the air

How does gravity affect motion on Earth?

• It causes objects to float.

• It pulls objects toward the center of the Earth.

• It pushes objects away from the Earth.

• It has no effect on motion.

What is inertia?

• The force that pulls objects together

• The tendency of an object to resist changes in its state of motion

• The speed at which an object moves

• The force that slows down moving objects

If you increase the force applied to an object, what happens to its acceleration?

• It decreases

• It increases

• It stays the same

• It stops

What happens when two forces act in the opposite direction?

• The object moves in the direction of the weaker force.

• The object moves in the direction of the stronger force.

• The object does not move.

• The object spins.

Which of the following would have the least inertia?

• A bowling ball

• A soccer ball

• A tennis ball

• A basketball
