Definitions
Energy is neither created nor destroyed, it only changes forms
Law of conservation of energy
At what point on the tracks of a roller coaster does the coaster have the most potential energy?
At the top of the hill (the highest point)
Energy stored in chemical bonds between atoms and molecules.
Chemical energy
What energy transformation takes place when you turn on a light?
Electrical energy is converted to light or heat energy
Stored energy; energy that is held by an object because of its position
Potential energy
At what point on the tracks of a roller coaster does the coaster have the most kinetic energy?
At the bottom of the hill (the lowest point)
Energy due to the movement of electrons through a conductor, like in a circuit.
Electrical energy
When you use a microwave to heat up food, which type of energy is being converted to which other type of energy?
Electrical energy is converted to heat energy
Energy of motion; energy an object has because it is moving
Kinetic energy
Would a ball have more gravitational potential energy when it is kicked in the air, or when it's on the ground?
When it is kicked in the air
Energy stored in the nucleus of an atom.
Nuclear energy
What type of energy transformation takes place when you turn on a flashlight?
Chemical energy to electrical energy to light energy
The energy that moves objects
Mechanical energy
When does a rubber band have the most potential energy?
When it is stretched out as far as it can go
Energy created by vibrations and carried by waves.
Sound energy
A hydroelectric dam is an example of what type of energy transformation?
Mechanical energy to electrical energy
The ability to do work
Energy
How can kinetic energy be increased?
By increasing the mass and speed
Potential energy stored in objects that can be stretched or compressed.
Elastic energy
What energy transformation takes place in the process of photosynthesis?
Light energy from the sun is converted to chemical energy
