The size of your ice skates affects your speed across the ice.

2.
How is velocity different from speed?

Velocity is speed and direction together.
d)
Velocity is not at all different from speed.
3.

What does friction do to a moving object?

slows it down

speeds it up

makes it rise

all of the above

4.

a)

Friction has to be applied to the ball.

b)

Force has to be applied to the ball.

c)

Speed has to be applied to the ball.

Inertia has to be applied to the ball.

5.
What is the relationship between heavy objects and inertia?
a)
Only heavy objects have inertia.
b)
Heavy objects have no inertia.
c)
Heavy objects have less inertia.

Heavy objects have more inertia.
6.
You are riding in the car with your grandfather, and he turns left. Why do you shift to the right?
a)
It takes you a moment to catch up with the new velocity of the car.
b)
You have more inertia than the car, so it takes longer for you to turn left.
c)
You had been sitting at rest until the force of the turn set you in motion.
d)
The car continued in the same velocity, but you had a different inertia.
7.
What does the second part of Newton’s first law say about objects at rest?
a)
They cannot move unless they have a lot of friction.
b)
If they are heavy, they will stay at rest, but if they are light, they will move.
c)
They will stay at rest unless an outside force makes them move.
d)
They have more inertia than objects in motion.
8.
Your neighbor is riding her bike around the block. When she slows down and turns a corner, what changes about her?
a)
her velocity
b)
her friction
c)
her speed only
d)
her balance
9.

What is the rate at which an object’s velocity changes called?

a)

inertia

b)

actualization

c)

acceleration

d)

completion

10.

What is inertia?

a)

the amount of force to start moving an object at rest

b)

an object’s velocity and its friction

c)

what keeps an object steady, at rest or moving consistently

the friction needed to slow an object in motion

11.
Your skateboard begins to slow down when you roll off the sidewalk and across gravel. What is at work?
a)
gravity
b)
friction
c)
balance
d)
all of the above
12.
What can be measured by acceleration?
a)
how much an object slows down

a)
an unbalanced force
b)
an inert force
c)
gravitational force
d)
friction
14.
If a hockey stick acts on a resting puck, what will happen?
a)
The puck will remain inert and the hockey stick will accelerate.
b)
The puck will balance on the end of your hockey stick until you drop it.
c)
The hockey stick will not move the puck, but the puck will move the hockey stick.
d)
The hockey stick will change the speed of the puck and make it accelerate
15.
Every time your cat’s paw hits her toy string, it swings away from her. How does this demonstrate Newton’s third law of motion?
a)
Objects with mass, such as your cat’s paw and toy string, will require inertia.
b)
Objects in action, such as the string toy, will experience force.
c)
For every motion from your cat’s paw, there is unbalanced inertia from the string.
d)
For every action your cat makes, there is an equal and opposite reaction from the string
