Give an example of convection, conduction and radiation. (That has not been said!)
Convection (current)- wind, pool water. Conduction (direct contact) - heating a branding iron, touching a heating blanket. Radiation (Space) - Oven, heater

What is potential energy?
Energy that is stored
200
What is chemical energy?
Chemical reactions taking place.
200
What is mechanical energy?
Energy in motion that is doing work
200
Difference bettween transfer and transformation?
Transfer is moving place to place (left to right or traveling through wires) and transformation is changing forms (potential to kinetic).
200
What is conduction?
Conduction is the transfer of energy through solid matter from particle to particle. Heat is conducted through a solid material. Pot on the oven heating.

Give me an example of Kinetic and Potential energy?
Kinetic- a ball rolling, Potential - a ball sitting on a hill about to roll
300
What is electrical energy?
Energy that creates light, heat and motion.
300
Explain to me a transformation with at least three energy forms in order?
Correct!
300
What is transformation mean?
When energy changes from one form to another.
Examples: Potential to Kinetic or Electrical to Light
300
What is convection?
Convection is the transfer of heat energy through a gas or liquid by movement of currents. EX: Boiling water or a hot oven.
400
What are the two main energy sources?
Kinetic and Potential
400
Wind Turbines are creating which energy source?
Mechanical

Free Be!
YAY!

What is the transformation of a lightbulb? Starting with the battery?
Chemical to Electrical to Light to Thermal
400
What is Radiation?
is electromagnetic waves which directly transport heat energy through space. (The heat travels through space). EX: SUN or Fire (you do not have to touch the heat source to recieve heat)
500
Give me three examples of kinetic and potential energy!
Potential: about to happen (stored energy)
Kinetic: Happening (in motion)

Waterfalls are what energy? and a lamp thats been on for awhile is?
