Mechanical Energy
All kinds of energy are measured in this unit.
What are Joules?
Seeing your image in a mirror is an example of this behavior of light.
What is reflection?
Thermal energy measures the transfer of this.
What is heat?
This kind of circuit has multiple pathways for an electrical current to flow through.
What is a parallel circuit?
A ramp is a good example of this simple machine.
What is an inclined plane?
Mechanical energy is made up of these two kinds of energy.
What is kinetic and potential energy?
This quality of waves affects a sound's volume.
What is amplitude?
All heat transfer moves in this direction.
What is from hot to cold?
These objects don't allow electrical currents to pass through them easily.
What is an insulator?
This formula is what is used in the second law of motion.
What is F = ma?
Kinetic energy is also known as energy in ________.
What is motion?
When the frequency of a sound wave increases, so does this.
What is pitch?
Mr. K burns his hand on a hot stove, using this kind of thermal energy transfer.
What is by touch?
A closed circuit allows this to flow through it easily.
What is an electric current (electricity)?
An object's speed can be measured by dividing this by time.
What is distance?
Mr. Davis places a marble at the top of a marble roller coaster track, giving it this type of energy.
What is potential energy?
Ms. Delaney launches a satellite with a solar sail, which uses this kind of light behavior to turn light energy into kinetic energy.
What is absorption?
The sun and microwave ovens are two examples of this kind of heat transfer.
What is radiation?
Electrical energy is created by a buildup of this subatomic particle.
What are electrons?
This describes an object's tendency to keep doing what it's doing, whether that be moving or staying put.
What is inertia?
Ms. Park shoots a bow and arrow. The arrow at one point has a kinetic energy of 100 J and a total mechanical energy of 130 J, meaning it has this much potential energy.
What is 30 J?
Ultraviolet rays have a higher frequency than visible light, meaning their wavelengths are this in comparison.
What are shorter?
An air fryer heats up the air around a food to cook it, using this kind of heat transfer.
What is through fluids?
This part of a circuit can also show where a light bulb or other device is in a circuit.
What is a resistor?
A lever is made up of these two parts.
What is a bar and fulcrum (pivot)?
