Types of Energy
Sound energy is...
energy present when an object produces sound
Describe what happens when you eat food and then move.
The food's chemical energy is transferred into your body. Then, you body transforms that chemical energy into kinetic energy so you can move/run
All movement is...
Kinetic energy
Electrical energy to light energy
Transformation
Energy transformation
When energy changes from one form to another
Thermal energy is...
Heat energy
Bonus 100 points if you said "the movement of particles"
What energy transfer do we see going from a wire to a light?
Electrical -> Radiant
100 bonus points if you said thermal too!
Stored energy is...
Potential energy
Chemical potential energy (food) turns into kinetic energy when a kid plays soccer
transformation
Light energy is also called
Radiant energy
Chemical Energy is...
energy stored in the bonds of atoms
What energy transformations do we see in a catapult?
Name 3
Potential, Kinetic, Elastic Potential, Mechanical, Sound
A car rolling down a large hill is...
Kinetic energy
the sun heating up the ground on a hot day
Transfer
Elastic Energy
the energy stored in something when you stretch or squish it
Bonus: 100 points if you mentioned that it returns to it's original shape or position
Sound, Radiant, Thermal, Mechanical
Name three types of energy in a circuit
Electrical, Radiant, Thermal
A ball at the top of a ramp is...
potential energy
Explain the transfers and transformations present in a flashlight
Chemical potential -> Electrical -> Light -> Thermal
Gravitational energy
Potential (stored) energy due to the height of something above Earth
Gravitational, Elastic, Chemical, Mechanical
Describe what the prefix trans- and the suffix -form mean.
Trans means across, different, or change
Form means type, shape, or form
Bonus: 100 points if you talked about what they mean together.
A swing swinging
Both!
Explain the difference between a transfer and a transformation
A transfer stays the same type of energy and just moves places while a transformation changes into a new type of energy.
Law of Conservation of Energy
Energy is neither created nor destroyed, only transferred or transformed
