Neil studied how a pulley helps move an object. Neil tied a rope to an object with a mass of 10 kilograms (kg) and attached it to a pulley. He then pulled down on the rope. When Neil pulled down on the rope, which did he MOST likely learn about the force required to lift the object?
It was half of the weight of the object.
It was equal to the weight of the object.
It was two times the weight of the object.
It was three times the weight of the object.
Students used rulers as levers during an investigation on simple machines and forces. They made the arms of the levers different lengths by how they placed the ruler on the desk. They put a box on the end of the ruler. Which ruler would require the greatest force to be able to lift the box off the desk?
Guy uses a manual can opener to open a can. Which BEST explains how the can opener makes it easier for Guy to open the can?

The illustration shows a person removing the lid from a crate with a crowbar. Which statement describes the force on the crowbar and the motion of the lid?
As the crowbar is pushed down, the lid moves down.
As the crowbar is pushed down, the lid moves up.
As the crowbar is pulled up, the lid moves down.
As the crowbar is pulled out, the lid moves up.
Refer to the electric circuit to answer the question that follows. Light bulb 2 burned out in this circuit. If voltage remains constant, what happens to the remaining light bulbs?

They get brighter.
They get dimmer.
They remain the same.
Some steep roads have an emergency exit ramp, known as a “Runaway Truck Ramp.” This ramp serves as a way off the road for drivers having difficulty slowing their vehicles. Which statement BEST describes how this inclined plane helps the driver of the vehicle?
It changes the direction of the force needed to slow the vehicle.
It changes the size of the force needed to move the vehicle.
It increases the distance required to move the vehicle.
It increases the force required to slow the vehicle.
Which circuit diagram shows three resistors connected in series?
Constance drew a diagram to show the flow of electricity in a flashlight. What would happen if Constance placed the cardboard circle between the two batteries?
The flashlight would not work.
The light would only be half as bright.
The cardboard would not affect the flashlight.
The flashlight would stay on if she turned off the switch.
