Quiz #2 - Newton's 1st and 2nd laws

What is Newtons 1st Law of Motion?

• Every action has an equal but opposite Reaction

• An object in motion/rest stays in motion/rest unless acted upon by an outside force.

• A larger mass object requires more force to move

Newton's Second law basically says that

• the more force applied to an object, the slower it will accelerate

• the more force applied to an object, the faster it will accelerate
