Forces/ Newton's Laws Quiz Study Guide
This quiz will describe different scenarios involving Newton's Laws and ask you to identify which
law goes with that type of motion. You should be able to justify your reasoning for your choices.

What to know:
What is a force?
Describe gravity and friction as forces. What is gravity, which direction does it act in? What is
friction, which direction does it act in?
1) Newton's First Law: Law of Inertia
Objects in motion will stay in motion, objects at rest will stay at rest, unless acted upon
by an unbalanced force
Ex: Be able to explain how Newton's first law is the reason why seat belts should be worn in moving
car.
1) Use Newton's first Law to describe what is happening in
this picture.
Why won't a soccer ball start moving on its own? What has to happen in order for the ball to start
moving?
2) Newton's Second Law:

Force = Mass x Acceleration ( The relationship between force, mass , and acceleration)
What are two ways to cause an object to accelerate faster?
Ex: You are trying to push with shopping cart full of groceries, according to Newton's second law what
are two things you could do to get the shopping cart to accelerate (speed up)
Why do objects with less mass accelerate faster than objects with more mass?
Newton's Third Law: Every action has an equal and opposite reaction

Be able to identify action and reaction forces
Draw and label the action and reaction forces on diagrams below, explain what is happening according
to Newton's 3rd Law of Motion.

Momentum:
Momentum = Mass x Velocity


What happens to momentum when the mass is increased?
What happens to momentum when the Velocity increases?
-What is the Law of Conservation of Momentum- Which of Newton's Laws does this correlate with?
-Define Centripetal force and in which direction does it act in? Draw a diagram.
