Which one is NOT a part of Newton's 1st Law?

• An object in motion remain in motion.

• An object at rest will remain at rest.

• An unbalanced force will change an objects motion.

• An object will never stop not matter what

Which is a common unbalanced force acting against applied forces?

• 0.60 V

• 15 V

• 1.7 V

Newton's first law is sometimes called:

• Law of friction

• Law of inertia

• Law of conservation of Energy

• Law of Conservation of Mass

Which of the following is the equation for Newton’s second law of motion?

• force = mass X acceleration

According to Newton’s 1st law, a moving object that is not acted on by an unbalanced force will

• eventually come to a stop.

• accelerate.

• remain in motion.
