• Situation A
• Situation B
• Situation C
• Situation D

Question 2

Question

• the opposite direction of motion.
• the same direction as motion.
• a direction toward an object.
• a downward direction.

Question 3

Question
Gravity moves in _____________.
• the opposite direction of motion.
• a direction toward an object.
• a downward direction.
• the same direction as motion.

Question
In which situation(s) is balanced forces being applied?
• Situation A
• Situation B
• Situation C
• Situation D

Question 5

Question
What is rolling friction?
• When round objects roll across a flat floor and both the object and floor are bent slightly out of shape.
• Air resistance acted on in both gases and liquids.
• A force that acts on objects that are NOT MOVING and is ALWAYS OPPOSING movement
• It is harder to start something moving, then to keep something moving that is already in motion (sliding friction).

Question 6

Question
What is static friction?
• Air resistance acted on in both gases and liquids.
• A force that acts on objects that are not moving and is always opposing movement.
• It is harder to start something moving, then to keep something moving that is already in motion (sliding friction).
• When round objects roll across a flat floor and both the object and floor are bent slightly out of shape.

Question 7

Question
What is fluid friction?
• When round objects roll across a flat floor and both the object and floor are bent slightly out of shape.
• It is harder to start something moving, then to keep something moving that is already in motion (sliding friction).
• A force that acts on objects that are not moving and is always opposing movement.
• Air resistance acted on in both gases and liquids.

Question 8

Question
What is sliding friction?
• When round objects roll across a flat floor and both the object and floor are bent slightly out of shape.
• It is harder to start something moving, then to keep something moving that is already in motion (sliding friction).
• A force that acts on objects that are not moving and is always opposing movement.
• Air resistance acted on in both gases and liquids.

Question 9

Question
Order of resistance of motion (most to least): ____________________________________.
• Rolling, Fluid, Sliding, Static
• Fluid, Rolling, Static, Sliding
• Static, Rolling, Sliding, Fluid
• Static, Sliding, Rolling, Fluid

Question 10

Question
Force is a scaler quantity only measuring magnitude and not direction.
• True
• False

Question 11

Question
What does Newton's 1st Law state?
• An object in motion tends to stay in motion but an object at rest tends to stay at rest.
• Force = mass · acceleration
• For every action, there is an equal but opposite reaction.

Question 12

Question
What does Newton's 3rd Law state?
• For every action, there is an equal but opposite reaction.
• Force = mass · acceleration
• An object in motion tends to stay in motion but an object at rest tends to stay at rest.

Question 13

Question
What does Newton's 2nd Law state?
• An object in motion tends to stay in motion but an object at rest tends to stay at rest.
• Force = mass · acceleration
• For every action, there is an equal but opposite reaction.

Question 14

Question
Which of Newton's three laws apply? When you put a book on a table and the table pushes on the book.
• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

Question 15

Question
Which of Newton's three laws apply? A person is pushed forward into their seat belt when a car stops.
• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

Question 16

Question
Which of Newton's three laws apply? A larger car takes more force to move than a smaller one.
• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

Question 17

Question

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

Question 18

Question
Which of Newton's three laws apply? A brick sits on a table until you push on it
• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

Question 19

Question
What is the difference between mass and weight?
• Mass is heavier than weight.
• Weight is mass but still including gravity.
• Mass is weight and scaler is a vector.
• No difference

Question 20

Question
Assume that a catcher in a professional baseball game exerts a force of -65 newtons. If the baseball has a mass of 0.145, what is the baseball's acceleration as it is being caught?
• -9.43
• -64.86
• -448.28
• -9.42

Question 21

• ... a greater mass ... harder ... lighter ... more ... more ...
• ... a greater mass ... easier ... lighter ... less ... less ...
• ... a lighter mass ... easier... heavier ... more ... more ...
• ... a lighter mass ... harder... heavier ... more ... more ...
• ... a lighter mass ... harder... heavier ... less ... more ...
• ... a greater mass ... easier ... lighter ... less ... more ...

Question 22

Question
How do sprinklers apply Newton's 3rd law of Motion? Choose the BEST answer.
• The greater the mass of the sprinkler, the harder it is for the sprinkler to turn.
• The sprinkler stays in motion unless you turn it off to make it at rest.
• Sprinklers spray out water, causing the sprinkler to move in the opposite direction in the shape of a circle.
• The lesser the mass of the sprinkler, the harder it is for the sprinkler to turn.

Question 23

Question
A force pulls an object up 3 N, but gravity pulls the object 3 N as well. Applied force pulls the same object to the left 20 N, but friction pulls the object 19 N. What is the Net Force of the object?
