Quiz on Newton's Laws of Motion

What does Newton's first law, also known as the law of inertia, state about an object?

• An object's speed increases with applied force.

• An object remains at rest unless acted upon by an external force.

• An object's motion is dependent on its weight.

• An object at rest tends to stay in motion.

According to Newton's second law, why does it take less force to move a bike than a car?

• Because a bike is lighter than a car.

• Because a bike is usually faster than a car.

• Because a bike has fewer wheels than a car.

• Because a car uses more fuel.

What happens according to Newton's third law of motion?

• Force equals mass times acceleration.

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

• Speed of an object decreases with time.

• An object at rest stays at rest.

What is 'force' as described in the text?

• A measure of an object's speed.

• The energy an object has due to its motion.

• An action that causes an object to move or change its shape.

• The resistance an object has to changes in its state of motion.

What does 'acceleration' describe?

• The time it takes for an object to reach its peak speed.

• The distance an object travels over time.

• The process of an object coming to a stop.

• The change in velocity of an object over time.
