Types of Energy
The two main categories of energy
What is Potential and Kinetic Energy?
Describe an object that has kinetic energy.
Points given at Mrs. Brockman's discretion. E.g. Anything in motion
Describe an object that has a high amount of potential energy.
Points given at Mrs. Brockman's discretion. e.g. top of a hill
The law of conservation of energy states...
What is energy cannot be created or destroyed?
Define potential chemical energy.
What is energy stored in chemical bonds between 2 or more atoms?
Type of energy that refers to the energy of an object in motion
What is kinetic energy?
This is where kinetic energy transforms into when an object's speed increases
What is thermal (heat) energy?
TRUE/FALSE: The height of an object does not affect the potential energy
What is FALSE?
Give an example of of energy being transferred from one object to another.
Points given at Mrs. Brockman's discretion. eg pulling back a rubberband & letting go
Define potential elastic energy
What is energy stored in objects that are stretched or compressed & will rebound to their original shape?
Give an example of an object or substance that has potential energy
Points given at Mrs. Brockman's discretion. e.g. Ball sitting on top of a hill
TRUE/FALSE: An object that is stationary does NOT have kinetic energy.
EXPLAIN.
What is true? Because stationary objects contain potential energy, they are not moving.
TRUE/FALSE: Potential energy is dependent on an object's mass.
What is true?
Explain how friction affects the conservation of energy.
What is friction generates heat thus transferring kinetic energy into heat energy and not potential energy?
Potential chemical energy is released by...
What is chemical reactions?
TRUE/FALSE: Objects can have energy as a result of their position
What is true?
Give an example of kinetic acoustic energy.
What is anything that makes a sound (musical instruments, airplanes, whales, etc)?
Who is my favorite soccer team?
What is Liverpool FC YNWA :)
How does the law of conservation relate to a roller coaster ride?
Law of Conservation of Energy is evident in a roller coaster ride as potential energy is converted to kinetic energy and vice versa, with the total energy remaining constant (discounting losses due to factors like friction).
Give an example of an object with elastic potential energy & how the energy is being transferred from PE to KE
Points given at Mrs. Brockman's discretion. e.g. bow & arrow PE=pulled all the way back is transferred to KE when letting go
Explain the difference between potential and kinetic energy.
What is potential is the store energy and kinetic energy is in motion?
Give an example of kinetic electromagnetic energy.
What is cell phones, wifi, radio, microwaves, x-rays, etc?
Describe an example of potential chemical energy.
What is food, coal, chemical batteries, photosynthesis, etc?
Mrs. Brockman's favorite food is...
What is chocolate, sushi & coffee?
Mrs. Brockman's childrens' names are... **SPELLING MATTERS***
What is Emry & Eyla?
