A bowling ball sitting motionless on a table exerts a downward force on the table. The force exerted by the table must be
continually changing with the ball.
equal to the force of the ball.
greater than the force of the ball.
less than the force of the ball.
If a book sitting on a flat table starts to move horizontally, it is most likely moving because
a balanced force is being applied.
a frictional force is being exerted.
a gravitational force is being exerted.
an unbalanced force is being applied.
The best example of balanced forces is a
car increasing speed.
bus parked in a garage.
ball kicked along a flat surface.
roller coaster slowing down on an incline.
Isaac Newton discovered the three laws of motion. Which example best illustrates Newton’s third law of motion, which describes action and reaction forces?
a vehicle rounds a curve and changes its acceleration
a heavier ball falls at the same speed as a lighter ball
a book slides forward on a seat when the car stops
a rocket takes off from the ground
Which graph could represent a car moving at a constant speed in a forward direction?
The graph shows the motion of four cars. All four cars are moving east.
Which car has a constant velocity?
1
3
2
4
In a game of tug-of-war, the people on each team pull with the amount of force shown.
In which direction will the center of the rope go?
to the west because the net force is greater in this direction
to the east because the net force is greater in this direction
to the west because the net force is less in this direction
to the east because the net force is less in this direction
In the diagrams the arrows represent forces exerted on the boxes. Which diagram represents a box that will remain stationary?

Which is most likely needed when describing the change in position of an object?
initial speed
constant rate
direction change
reference point
Megan is sitting in her car in a parking lot. The car next to her pulls forward.

Why is it important for basketball players to wear shoes with tread when playing?
to increase the speed of the player
to decrease the force between the player and the floor
to increase friction between the floor and the player’s feet
to decrease the amount of force needed for the player to move

According to the Law of Conservation of Momentum, when two objects collide:
both objects lose momentum.
both objects gain momentum
momentum is neither lost nor gained, but can be passed from one to the other
momentum is always lost or gained
