In the absence of friction, if a force acting on a moving object stops acting, the object will:
stop moving.
move at a slower speed.
speed up.
keep moving at a constant speed.
A change in position of an object is its ___________.
motion
acceleration

Three forces are acting upon the box shown in the diagram below.
Assuming there is no friction between the floor and the ground, how will these forces affect the position of the box?
The forces will cause the box to move to the left.
The forces will cause the box to move to the right.
The forces will cause the box to collapse to the ground.
The forces will be unable to move the box in any direction
Earth has a large mass, which requires a _______ force to _________ its motion.
small/maintain
small/change
large/maintain
large/change
This diagram shows a segment of a roller coaster. As the roller coaster car moves from Point A to Point B, its speed increases. Why?
The force of friction decreases on the downhill track.
The inertia of the roller coaster car decreases.
Balanced forces act on the roller coaster car.
Unbalanced forces act on the roller coaster car.
hich of the following best completes this sentence? In every interaction, forces occur in ___________.
specific places
single unit
pairs
one direction only
According to Newton's third law, which statement describes why it is difficult to walk on an icy pond?
Your shoes push against the ice, but the ice cannot push your shoes.
Extremely low friction between your shoes and the ice eliminates traction to move you forward.
The ice is cold so it crumbles as you push against it.
The ice melts under your shoes, making it much more slippery.
Forces that are equal in magnitude but opposite in direction are:
balanced forces
unstoppable forces
unbalanced forces.
universal forces.
Mass is a measure of which of the following quantities?
energy
matter
space
motion
On a "spacewalk," an astronaut in orbit around the Earth is using a wrench to do a repair on the outside of her spacecraft. What would happen to her wrench if she accidentally let go of it?
The wrench would remain in orbit around the Earth.
The wrench would immediately fall straight to Earth.
The wrench would stop moving in the spot where she let it go.
The wrench would fly off into space in a straight line at a constant speed.
When one figure skater pushes on another, both skaters move in opposite directions. Which of Newton's laws of motion best explains why this occurs?
Newton's First Law
Newton's Second Law
Newton's Third Law
Newton's Fourth Law
The force needed to move an object depends upon:
the mass of the object
the volume of the object
the density of the object
the shape of the object
A rocket's mass is reduced by half, but the force pushing it through space remains the same. What will happen to the rocket's acceleration?
It will stay the same.
It will be reduced by half.
It will double.
it will quadruple.
If you are pushing equally on two objects and one of the objects has three times more mass than the other, then the more massive object will experience __________ the less massive object.
three times the acceleration of
nine times the acceleration of
one third the acceleration of
the same acceleration as
Mary is driving on a straight road. When a deer jumps in front of her, she turns her car sharply to the left. What will happen to loose objects inside the car?
The loose objects will tend to move to the left inside the car.
The loose objects will tend to move to the right inside the car.
The loose objects will tend to move toward the front of the car.
The loose objects will tend to move toward the back of the car.
Students visit an amusement park to observe the kinds of forces acting on the riders of a rollercoaster. The students formulate the following hypotheses based on their observations. Which of these hypotheses would be best supported by evidence?
The force needed to start the rollercoaster car does not depend on the masses of the riders.
Gravity provides the force needed to move the car throughout the entire ride.
Seatbelts work against inertia during the ride.
Acceleration of the cars always works opposite gravity.
