Newtons Laws Of Motion

Which of the following was NOT a profession or field of study Sir Isaac Newton was known for?

• Natural philosopher

• Astronaut

• Mathematician

• Astronomer

What period is referred to as the Scientific Revolution?

• 1642 - 1726

• 1543 - 1687

• 1700 - 1800

• 1492 - 1600

Newton's First Law of Motion states that an object in motion tends to stay in motion, and an object at rest tends to stay at rest, unless acted on by some force. What is this tendency called?

• Gravity

• Acceleration

• Inertia

• Momentum

What is friction?

• A force that causes objects to accelerate

• The resistance one surface or object encounters when moving against another

• The force that pulls objects towards the center of the Earth

• The tendency of an object to stay in motion or at rest

Which equation represents Newton's Second Law?

• F = M + A

• F = M / A

• F = MA

• F = A / M

What is mass?

• The speed at which an object moves.

• The amount of stuff that makes up something.

• The force applied to an object.

• The change in an object's speed or direction.

How does an object's mass affect the force needed to move or stop it?

• More mass makes it easier to move but harder to stop.

• More mass makes it harder to move or stop.

• Less mass makes it harder to move or stop.

• Mass has no effect on the force needed.

What principle is described by Newton's Third Law?

• An object at rest stays at rest.

• Force equals mass times acceleration.

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

• Objects with more mass accelerate faster.
