1.
While you are ice skating with your friends, you push off from one end of the rink and slide forward. Based on Newton's First Law of Motion, what is true?
a)
You will lose your balance and fall over before you reach the middle of the ice rink.
b)
The force of gravity will make you keep your velocity until your friends make you stop.
c)
You will continue to slide across the ice until a force makes you stop or change directions.
d)
The size of your ice skates will determine how quickly or slowly you travel across the ice.
2.
How is velocity different from speed?
a)
Velocity is when an object moves in reverse.
b)
Velocity is the direction an object moves in and has nothing to do with speed.
c)
Velocity is speed and direction together.
d)
Velocity is not at all different from speed.
3.
What does friction do to a moving object?
a)
makes it rise
b)
slows it down
c)
speeds it up
d)
all of the above
4.
Your firend kicks a soccer ball, and it stops a few feet from you. What needs to happen to it in order for it to return to your friend?
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.
d)
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.
d)
Heavy objects have more inertia.
6.
Your neighbor is riding her bike around the block. When she slows down to turn a corner, what changes about her?
a)
her velocity
b)
her friction
c)
her speed only
d)
her balance
7.
What can be measured by acceleration?
a)
How much an object slows down.
b)
How much an object speeds up.
c)
An object changes its direction
d)
all of the above
8.
Every time your cat's paw hits her toy string, it swings away from her. How does this demonstrate Newton's third law?
a)
Objects with mass, such as the 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 form the cat's paw, there is an unbalanced inertia from the string.
d)
For every action your cat makes, there is an equal and opposite reaction from the string.
9.
What happens when two objects, such as a baseball and a bat, collide?
a)
One remains still while the other one moves in the same direction.
b)
They hit each other with the same force in opposite directions.
c)
They hit each other with unequal force in opposite directions.
d)
They hit each other with the same force in the same direction.
10.
When two objects with unequal mass collide, what will they do?
a)
accelerate at different rates.
b)
Accelerate in the same direction.
c)
Come to a complete stop.
d)
Continue at the same velocity.
