A car is stuck in the mud. Three people are pushing the car, but the car is not moving. Why is the car not moving even though a force is being exerted on it?
Cars are too large to be affected by forces.
A force in the opposite direction balanced the push.
The people were not strong enough to exert a force on the car.
The force of gravity is so strong that the people cannot push hard enough to move the car.

Eli is pushing the box with a force, which is shown by the arrow. The box does not move. What keeps the box from moving even though Eli is pushing on it?
Eli is pushing the box in the wrong direction.
There is too much air resistance for the box to move.
The force of gravity opposes the force exterted by Eli.
The force of friction opposes the force exerted by Eli.
The picture shows a beaker that contains a mixture of salt water.
Which of the following pieces of equipment should be used to separate this mixture?
magnet
balance
funnel
hot plate
When you ski down a hill you move faster and faster. Then at the bottom of the hill you eventually stop moving. What causes you to stop?
No force is acting upon your skis on the level surface, so you stop moving.
After you reach the bottom of the hill, you run out of energy, so you stop moving.
Friction between your skis and the ground is an unbalanced force that changes your motion.
Gravity affects you when you are skiing downhill, but there is not gravity on the level surface.
Which best describes a parallel circuit?
Electricity flows along one pathway.
The flow of electricity comes from one source.
Electricity flows along more than one pathway.
The flow of electricity comes from more than one source.
Which of these correctly describes a change in state of water?
liquid water -> melts -> solid water
liquid water -> boils -> water vapor
solid water -> condenses -> liquid water
water vapor -> evaporates -> liquid water
