What must occur to a shopping cart at rest in order to make it roll forward?
A force must be provided to overcome gravity.
Balanced forces must be acting upon the cart.
An unbalanced force applied to the cart pushing or pulling it forward.
The unbalanced force acting upon it must be smaller than that of friction.
A basketball rolls to a stop along a gym floor without anyone touching it. What answer choice BEST explains why this occurred?
The initial force that started the ball ran out.
The opposing force of friction stopped the ball.
The natural state of the ball is not to be in motion.
The force of gravity slowed the ball until it stopped.
As Jack pulls his wagon down the street it moves faster and faster. Jill, sitting a few meters ahead on the sidewalk, wants to slow Jack's wagon down so that it travels with a constant speed.
How can Jill accomplish her goal?
Sit in the wagon so that it begins to slow down.
Push Jack away from the wagon so that he is no longer pulling it.
Pull on the wagon in the opposite direction with twice Jack's force.
Pull on the wagon in the opposite direction with a force equal to Jack's.

A space station looks like a large wheel. the wheel rotates constantly. The inside of the wheel is the floor of the space station. This spinning motion simulates gravity. Explain how this works.
The spinning motion simulates the rotation of the earth.
Astronauts must push on the floor and apply a force on it to make it move.
All object in the spaceship require a force from the floor or they would not move.
Circular motion requires an acceleration to change direction. This is created by a force that the floor exerts on objects on the inside of the wheel.
Why does light behave as shown in the image when it passes from air to glass?
Light is scattered on the surface of the glass.
Light slows down when it passes into a denser medium.
Light is partially reflected on the surface of the glass.
Light splits into its constituent colors when it passes through glass.
You see an image of yourself in a mirror because light waves are
diffracted.
reflected back at you.
refracted through air.
refracted to a focal point.
What happens when light strikes a translucent object?
All of the light passes through the object.
All of the light is reflected by the object.
None of the light can pass through the object.
Some of the light passes through, and some of the light is absorbed or scattered by the object.
What happens when light strikes an opaque object?
All of the light passes through the object.
All of the light is reflected by the object.
None of the light passes through the object.
Some of the light passes through and some of the light is absorbed or scattered by the object.
