1.
While you're 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)
You will continue to slide across the ice until a force makes you stop or change direction.
c)
The force of gravity will make you keep your velocity until your friends make you stop.
d)
The size of your ice skates will determine how quickly you travel across the ice.
2.
How is velocity different from speed?
a)
Velocity is when an object goes in reverse.
b)
Velocity is the direction an object moves in and it 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 friend 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.
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 coninued in the same velocity but you have 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.
