What is Potential Energy?
What type of energy transformation occurs when wood burns in a campfire?
What is Chemical → thermal and light.
Heat transfer through direct contact is called what?
What is conduction.
What does the Law of Conservation of Energy state?
What is Energy cannot be created or destroyed, only transformed.
Why do white cars stay cooler than black cars?
What is White reflects more radiant energy.
Which form of energy increases with velocity?
What is Kinetic Energy?
What energy change happens in a solar panel charging a phone?
What is Light → electrical
Which type of heat transfer occurs in boiling water?
What is convection?
In a closed system that’s isolated from its surroundings, like a pendulum or roller coaster, what happens to the total amount of energy even as it changes form?
What is The total energy remains constant. It is conserved.
How does a solar oven melt chocolate?
What is Radiation (Light) is absorbed as heat energy.
A stretched rubber band ready to fly holds what type of energy?
What is Elastic Potential Energy?
Turning on a flashlight converts what energy into what? (3 changes)
What is Chemical → electrical → light
Feeling warmth from the sun without touching anything is an example of what?
What is radiation?
When potential energy decreases, what usually increases?
What is Kinetic energy.
What process allows a smell to spread across a room?
What is diffusion caused by molecular motion.
At the bottom of the rollercoaster hill, most of the energy is what type?
What is Kinetic Energy?
A wind turbine generating power is an example of what energy transformation?
What is Mechanical → electrical.
Why are oven mitts good insulators?
They’re made of cloth, which reduces heat transfer.
Doubling the height of the pendulum bob does what to its potential energy?
What is Doubles It
How does a roller coaster demonstrate the conservation of energy?
What is Energy shifts between potential and kinetic as it moves up and down.
When a pendulum reaches the highest point, what happens to its energy?
What is Kinetic -> Potential
Describe how energy changes when gasoline combusts inside a car engine.
What is Chemical → thermal → mechanical.
Explain how heat moves between a can and a cup in an experiment where the can is placed inside of a cup. The metal can was filled with 80°C water and placed into the styrofoam cup containing colder water, 10°C. The students predicted that the water in the metal can would decrease in temperature while the water temperature inside the cup would increase
Through particle collisions transferring kinetic energy.
Juan and Kai dropped their pendulum bob from 0.5 meters and then from 1 meter. If the mass stayed the same, how would this change affect the bob’s potential energy?
What is the energy would double. Height directly affects potential energy.
What variable most affects the swing time of a pendulum?
What is String length.
