'From what to what'....describe the energy transformation that occurs when a log is burning. 'starts as...changes to'
What is chemical (wood can burn) to heat or light (fire)
100
This form of energy is when electrons are being passed from one atom to the next.
What is "Electrical Energy"
100
The ability to cause change
What is Energy
100
Write all 3 parts to the Law of Conservation of Energy
What is 1. Energy cannot be created or destroyed 2. Energy can only be transformed 3. The total amount of energy in the UNIVERSE does not change
100
What is the unit use for energy
What is JOULE
200
'From what to what'....describe the energy transformation that occurs when a boy goes down a slide 'starts as...changes to'
What is "gravitational to motion"
200
This form of energy in the bonds of atoms and molecules is released when things burn or when our body digests food we eat.
What is Chemical Energy
200
The energy an object has due to its motion is called
What is Kinetic Energy
200
True or False. The total amount of kinetic energy in a ball falling increases.
What is "TRUE"...the ball is going faster, so the KE increases
200
What are the 2 factors that influence an objects kinetic energy?
What is MASS and SPEED
300
'From what to what'....describe the energy transformation that occurs when fan is turned on 'starts as...changes to'
What is "electrical to motion"
300
This form of energy moves in waves, vibrating molecules as it transfers from one molecule to the next.
What is "Sound Energy"
300
Transfer or Transform? One domino hitting another domino causing it to move.
What is Transfer (movement to movement, no change in form)
300
TRUE/FALSE The total amount of Potential Energy increases at a ball falls
What is FALSE The ball is losing height, so the Potential Energy is going down
300
What are the 2 factors that determine an objects potential energy?
What is MASS and HEIGHT(POSITION)
400
'From what to what'....describe the energy transformation that occurs when someone claps their hands in applause. 'starts as...changes to'
What is "motion to sound"
400
This form of energy is released when the nucleus of atoms are broken
What is Nuclear Energy
400
The energy an object has due to its position is called
What is Potential Energy
400
Describe the relationship between potential energy and kinetic energy as a ball is falling "Kinetic energy is going **, Potential Energy is going **"
What is Kinetic energy is going up, potential energy is going down
400
How many forms of energy are there? (1, 2, 3, or many)
What is MANY
500
'From what to what'....describe the energy transformation that occurs when a hammer is used to drive in a nail. 'starts as...changes to'
What is "mechanical to motion"
500
This form of energy is based on how fast an objects molecules are vibrating.
What is "Thermal/Heat Energy"
500
This proves how energy cannot be created or destroyed **Bonus 100pts if you can give the last name of the scientist who demonstrated this law..spelling counts**
