Rubbing two wooden sticks together can sometimes result in a fire. What would increase the probability of a fire starting?
Using longer sticks.
Rubbing the sticks together more quickly.
Holding the sticks higher off the ground.
None of the answers are correct.
Which statement most accurately describes the Law of Conservation of Energy?
Energy can not be created or destroyed but it can change from one type to another.
Energy is created from the Earth and is destroyed when we use it.
Energy should be saved (conserved) for use in the future.
All forms of energy can be classified as either potential or kinetic.
The efficiency of an average gasoline-powered car is about 20%. This means,
The gas tank needs to be 20% filled with gasoline for motion.
The car uses 80% of the energy stored in the gasoline for motion.
The car uses 20% of the energy stored in the gasoline for motion.
The car wastes 20% of the energy stored in gasoline.
Hat energy transformation takes place when a radio is plugged in and turned on?
Kinetic to potential
Electrical to sound
Wire to radio waves
Battery to Motion
When you open the door to a refrigerator for a minute, what happens?
Thermal energy in the refrigerator is transferred to the air outside the refrigerator.
Thermal energy in the air outside the refrigerator is transferred to the inside of the refrigerator.
The temperature of the air inside the refrigerator decreases.
The temperature of the air just outside the refrigerator increases.
Cory noticed that the hood of the car was hot after driving it for a while. What energy transformation was she noticing?
Chemical energy --> thermal energy
Thermal energy --> motion (kinetic)
Temperature energy --> braking energy
Motion (kinetic) --> light energy
Which formula below is NOT correct?
Speed = Distance / Time
Time x Speed = Distance
Velocity = (Distance / Time) + Direction
Velocity = (Distance / Time)
The following methods will melt an ice cube quickly, except?

Which of the following is an example of chemical energy being transformed into thermal energy?
A light is switched on.
A ball drops.
A match is burned.
An electric fire is switched on.
A liquid evaporates when the faster-moving molecules escape from the liquid. When this happens:
The temperature of the liquid decreases.
The temperature of the liquid increases.
The temperature of the liquid stays the same.
The temperature of the liquid increases until it reaches room temperature.
Heating an object to a higher temperature increases that objects:
Thermal Energy
Potential Energy
Chemical Energy
Kinetic Energy
