Create a free body diagram for a book resting on a table. Draw and label all appropriate forces.

A baseball player hits a home run. Which of the following describes the forces exerted between the bat and the ball?

• The forces are equal and opposite

• The force from the bat is much larger than the force from the ball

• The force from the bat is much smaller than the force from the ball

• The force from the bat is the only force present

Assuming applied force is constant, what will happen to the acceleration of an object if its mass increases?

• Acceleration will remain the same

• Acceleration will increase

• Acceleration will decrease

• Mass has no impact on an objects acceleration

Describe a scenario that proves one of Newton's Laws of Motion. Be sure to indicate which law is proven by your scenario.

What is the force due to gravity on Earth?

• 9.8 m²/s

• 9.8m/s²

• 9.8m²/s²

• 9.8m/s

A space shuttle only has enough fuel to get it out of Earth’s atmosphere. Once the space shuttle is in space (where there is no friction/ air resistance) it will continue moving even without any fuel because of ________.

• Newton's First Law
• Newton's Second Law
• Newton's Third Law
• The Law of Space and Redundancy

What is the weight of a 10kg object on Earth and on the Moon? (Moon gravity = 1.62m/s²)

How much force does a student need to apply to a 15 kg object for it to accelerate at a rate of 3m/s2?

• 5N

• 0.2N

• 18N

• 45N

An object on Earth weighs 100N. How fast would it accelerate if a student applied 15N of force to the object?

Which of the following objects has the least inertia and why?
Tennis ball, Honda Civic, Mr. Leiter, iPhone, Sheet of paper, Trash can

• The Honda Civic, because it has the most mass

• The Sheet of Paper, because it has the least mass

• The Tennis Ball, because it has the least mass

• The Trash Can, because it has the most mass
