Identifying
Energy
Energy
The ability to do work or cause change
What is Kinetic Energy?
Energy in motion.
What is Potential energy?
Energy that is stored.
Name 3 energy sources
Examples: Solar, wind, human powered, hydroelectric(water), fossil fuels, natural gas, nuclear fusion, and more
True or False: Can objects make their own energy?
False. Objects get energy from other objects that have energy.
What is the force exerted on an object that causes it to move?
(Hint: starts with w)
Work
Which is not an example of Kinetic energy?
Mechanical, Chemical or Electric?
Chemical
Which is not an example of Potential energy?
Mechanical, Thermal, or Electric?
Thermal is a type of Kinetic energy
Give an example of renewable energy
Examples could include: wind, solar, hand-crank flashlights and more
Fill in the blank: Energy-capturing backpacks, bikes, rocking chairs and knee braces work because when you move with these objects, you are _______ a generator.
Moving, spinning, turning
What is energy transfer?
Movement of energy from one place or object to another
Energy that is caused by the movement of electromagnetic waves is an example of what kind of Kinetic energy?
Radiant energy
The energy stored in the nucleus of an atom is an example of what kind of potential energy?
Nuclear Energy
What is a Generator?
A device used to convert kinetic energy (more specifically mechanical energy) into electrical energy.
Put energy system in order:
Generator, Crank, Flywheel, Crank, Battery, Light
1. Crank
2. Flywheel
3. Generator
4. Battery
5. Light
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed
What is Sound Energy? Give an example
Sound energy is energy in the form of wave motion. Vibrations spread in all directions as one vibrating object touches another object, making it vibrate.
Example: Speakers playing music
What is Chemical Energy? Give an example
Energy that stored in chemical substances.
Examples: batteries, fossil fuels, food
What would be a good energy source for a rescue team to use in a cave? Why?
A hand-crank flashlight would be a good energy source because it does not rely on electricity or the sun, instead it is human powered
Describe a system that could power a clock
Example 1: sun -> solar panel -> battery -> clock
Example 2: fossil fuels -> electric plant(generator) -> Power outlet -> battery -> clock
We identified 3 main parts in a scientific argument. Put them in order:
Evidence, Reasoning, Claim
1. Claim
2. Evidence
3. Reasoning
Give an example of Mechanical Kinetic energy being converted into Mechanical Potential energy.
Example 1: Winding up a wind-up toy.
Example 2: Pushing down a spring.
Give an example of Electric Potential energy being converted to Electric Kinetic energy.
Example: A charged battery powering a clock.
If a town lived next to a waterfall, what would be a good energy source for them to build?
A hydroelectric plant
How does a Hydroelectric Power Plant generate electric energy?
Mechanical Kinetic energy from falling water turns a turbine in a generator which is then converted to Electric Potential energy.
