it will require a lot of force to get it to fly
it will stay in flight unless something stops it, or it will stay unless something moves it.

Why don’t skateboarders keep flying through the air when they launch off a ramp?
the force of gravity works against the skateboarders' inertia

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?
You will lose your balance and fall over before you reach the middle of the ice rink.
You will continue to slide across the ice until a force makes you stop or change direction.
The force of gravity will make you keep your velocity until your friends make you stop.
The size of your ice skates will determine how quickly or slowly you travel across the ice.
How is velocity different from speed?
Velocity is when an object goes in reverse.
Velocity is the direction an object moves in, and it has nothing to do with speed.
Velocity is speed and direction together.
Velocity is not at all different from speed.
What does friction do to a moving object?
makes it rise
slows it down
speeds it up
all of the above
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?
Friction has to be applied to the ball.
Force has to be applied to the ball.
Speed has to be applied to the ball.
Inertia has to be applied to the ball.
What is the relationship between heavy objects and inertia?
Only heavy objects have inertia.
Heavy objects have no inertia.
Heavy objects have less inertia.
Heavy objects have more inertia.
You are riding in the car with your grandfather, and he turns left. Why do you shift to the right?
It takes you a moment to catch up with the new velocity of the car.
You have more inertia than the car, so it takes longer for you to turn left.
You had been sitting at rest until the force of the turn set you in motion.
The car continued in the same velocity, but you had a different inertia.
What does the second part of Newton’s first law say about objects at rest?
They cannot move unless they have a lot of friction.
If they are heavy, they will stay at rest, but if they are light, they will move.
They will stay at rest unless an outside force makes them move.
They have more inertia than objects in motion.
Your neighbor is riding her bike around the block. When she slows down and turns a corner, what changes about her?
her velocity
her friction
her speed only
her balance
The rate at which an object’s velocity changes is called what?
inertia
actualization
acceleration
completion
What is inertia?
the amount of force necessary to make an object at rest start moving
an object’s velocity combined with its friction
what keeps an object steady, whether at rest or moving at the same velocity
the amount of friction necessary to slow down an object in motion
Your skateboard begins to slow down when you roll off the sidewalk and across gravel. What is at work?
gravity
friction
balance
all of the above
What can be measured by acceleration?
how much an object slows down
how much an object speeds up
an object’s change in direction
all of the above
Your dog’s wagging tail knocks over the cup of pencils sitting on your desk. What kind of force is his tail?
an unbalanced force
an inert force
gravitational force
friction
If a hockey stick acts on a resting puck, what will happen?
The puck will remain inert and the hockey stick will accelerate.
The puck will balance on the end of your hockey stick until you drop it.
The hockey stick will not move the puck, but the puck will move the hockey stick.
The hockey stick will change the speed of the puck and make it accelerate.
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?
Objects with mass, such as your cat’s paw and toy string, will require inertia.
Objects in action, such as the string toy, will experience force.
For every motion from your cat’s paw, there is unbalanced inertia from the string.
For every action your cat makes, there is an equal and opposite reaction from the string.
What happens when two objects, such as a baseball and a bat, collide?
One remains still while the other one moves in the same direction.
They hit each other with the same force in opposite directions.
They hit each other with unequal force in opposite directions.
They hit each other with the same force in the same direction
What does an object do when it accelerates?
It speeds up.
It moves in the opposite direction.
It changes speed and direction.
all of the above
What determines an object’s mass?
amount of matter
amount of friction
amount of force
amount of gravity
When two objects with unequal mass collide, what will they do?
accelerate at different rates
accelerate in the same direction
come to a complete stop
continue at the same velocity
A softball and a volleyball collide with equal speed, and then they accelerate at the same rate. What must be true about the masses of the objects?
The softball has more mass than the volleyball.
The softball and the volleyball have equal mass.
The volleyball has more mass than the softball.
It is impossible to compare the mass of the softball and the volleyball.
During P.E., your soccer ball collides with the goalie. What happens to the soccer ball?
It stops moving completely.
It accelerates at the same rate and in the same direction as the goalie.
It accelerates more and in a different direction than the goalie.
It continues moving at the same velocity as before.
Which of these can cause a moving object to change direction?
inertia
velocity
force
mass
What is gravitational force?
the force that keeps people from moving
the force of attraction between any two objects
the force that makes inert objects start moving
the only force that changes an object’s velocity
Where is an object’s center of gravity?
the exact center of its mass
the part that is closest to the Earth
any part of an object, as long as it has mass
all of the above
A paperclip and a computer are sitting on your desk. What is true about the gravitational force of these two objects?
The paperclip attracts the computer with less gravitational force than the computer attracts the paperclip.
The computer and the paperclip attract each other with equal gravitational force.
The computer attracts the paperclip with less gravitational force than the paperclip attracts the computer.
There is no gravitational force between the paperclip and the computer.
Why don’t we see the ground coming toward us?
We have less gravitational force than the Earth.
We have more inertia than the Earth.
We have less mass than the Earth.
We are already standing on the Earth.
Why doesn’t the moon crash toward the Earth’s surface?
It has very little inertia, so it stays in the sky and floats through space.
It has a lot of mass, so it feels the Earth’s gravitational force less than smaller objects do.
It has more mass than the Earth, so it stays in one place while the Earth orbits it.
It is too small to fall through the Earth’s atmosphere and reach the Earth’s surface.
Why is it impossible to “defy gravity”?
There is no gravity.
You can’t defy gravity without going to another planet.
Gravitational force exists every place where there are two objects.
Nothing has enough force to resist gravity..
