Both A and B
C. None of the above
The force that two surfaces exert on each other when they are in contact.
inertia
mass
gravity
friction
Match the following types of friction with their characteristics:
Static friction
Friction that occurs when an object is not moving
Rolling friction
Friction that occurs when an object rolls over a surface
Fluid friction
Friction that occurs when an object moves through a fluid
Sliding friction

What happens to the gravitational force between two objects when their masses are increased?
The force increases
The force decreases
The force remains the same
The force becomes zero
What is the SI unit of mass?

Ounce
What does the first law of motion state?
An object at rest will remain at rest unless acted on by a nonzero net force.
An object in motion will continue to move at a constant velocity unless acted upon by a nonzero net force.
Both a and b.
None of the above.
Which of the following best describes inertia?
An object's tendency to resist a change in motion.
The force that moves an object.
The speed of an object.
The direction of an object's motion.
What is the formula for calculating force?
Force = mass x acceleration.
Force = mass / acceleration.
Force = acceleration / mass.
Force = mass + acceleration.

According to Newton's third law of motion, if one object exerts a force on another object, what happens?
The second object exerts a force of equal strength in the opposite direction.
The second object exerts a force of equal strength in the same direction.
The second object exerts a force of greater strength in the opposite direction.
The second object exerts a force of greater strength in the same direction.
Which of the following is an example of an action/reaction pair?
A car accelerating on a highway.
A swimmer moving through the water by exerting force with her hands.
A ball rolling down a hill.
A person sitting on a chair.
According to Newton's second law, if the mass increases and the force stays the same, the
(a) .
Acceleration increases.
Acceleration remains the same.
Acceleration becomes zero.
Acceleration decreases.
Match the following statements with Newton's laws:
Objects change their motion when force is applied.
Newton's First Law
The acceleration depends on the strength of the force and the mass of the object.
Newton's Second Law
Whenever a force acts on an object, that object applies an equal and opposite force back.
Newton's Third Law
How is the momentum of a moving object calculated?
Mass + Velocity
Mass - Velocity
Mass x Velocity
Mass / Velocity
How can a heavy moving van have the same momentum as a small motorcycle?
Momentum equals mass times velocity, so the truck would need to be moving more slowly than the motorcycle.
The motorcycle would need to be moving more slowly than the truck.
Both the van and the motorcycle need to have the same mass.
The van needs to have a higher velocity than the motorcycle.
Calculate what is the momentum of a 750-kg car traveling at a velocity of 25 m/s?
a. 18,750 kg·m/s
b. 1,875 kg·m/s
c. 18,750 kg·m

0.06 m/s
0.06 kg
What would happen if you could turn off a centripetal force?
The object would continue to move in a circle.
The object would fly off in a straight line.
The object would stop moving.
The object would move in a zigzag pattern.
Why do satellites follow a curved path around Earth?
Because of the Earth's magnetic field.
Because of the curved surface of the Earth.
Because of the gravitational pull of the moon.
Because of the wind resistance in space.
