Which of the following demonstrates kinetic energy?
A person running
A person about to slide down a ramp
A pitcher holding a ball
Which diagram correctly identifies the force of friction on the box?
Which of these statements correctly describes these objects as conductors or insulators?
Group 2 objects are insulators because electrical energy can move around them.
Group 1 objects are conductors because they force electricity to flow in the opposite direction
Group 1 objects are conductors because electrical energy can flow easily through them
Group 2 objects are insulators because electricity is attracted to them
A student conducted an investigation testing the strength of an electromagnet. The independent variable in this investigation was
NUmber of paperclips attracted
Number of times the wire was coiled
Voltage of the battery
Length of the insulated wire
A student picked up two objects from the table. One of the objects was opaque, and the other was transparent. Which of these could be the objects that the student picked up?

Students investigated the way in which light travels using different objects. At the conclusion of the investigation, they determined that light travels in a straight path until it hits an object. What observation did they most likely make?
Shining a flashlight into a prism caused the light to bounce back.
Light was observed when the students shined a flashlight into a mirror.
When placing a baseball in a path of light, the students noticed the light passed through the baseball.
The straw appeared broken or bent when immersed in a cup of water.

What was the first energy transformation that took place as the students charged the vehicle's power source as shown in figure 1
Thermal energy was changed from another form of energy
Electrical energy was changed from another form of energy
Kinetic energy was changed to thermal energy
Electrical energy was changed to kinetic energy
Based on the average time in the data tables, on surface 1 the vehicle moved
Farther than it moved on surface 2
Faster than it moved on surface 2
At the same speed it moved on surface 2
Slower than it moved on surface 2
Explain why the girl's hair is sticking to the balloon.
The balloon is negatively charged and the girl's hair is negatively charged so they both stick to one another.
The balloon is positively charged and the girl's hair is positively charged so they both stick to one another.
The girl's hair and the balloon have the exact same charge and therefore, they both stick to one another.
The girl's hair has the opposite charge of the balloon and therefore, they stick to one another.
