The energy associated with moving objects.
What is kinetic energy?
100
Energy Transfer.
What is the passing of energy from one object to another?
100
The equation for GPE.

100
Equation for kinetic energy
What is KE = 1/2mv^2?
200
The potential energy stored in the bonding of particles that make up matter.
What is chemical potential energy?
200
The energy that an object has due to its position.
What is Gravitational Potential Energy?
200
Energy Transformation.
What is the changing of energy from one form of energy to another form of energy?
200
The equation for power.
What is power = energy transferred/time?
200
A resistive force that acts to prevent slipping between two contact surfaces.
What is friction?
300
The random and very disorganized kinetic energy of the particles in a substance.
What is heat energy?
300
(Define) Law of Conservation of Energy.
What is energy cannot be created nor destroyed? Energy can only be transferred from one object to another or transformed from one form to another, but the total amount of energy never changes.
300
A map of what happens to the energy, where it goes, and how it changes.
What is an energy chain?
300
Cause of an object's weight. (What causes weight?)
What is an object's weight is caused by the gravity of the Earth pulling the object downward towards its surface?
300
Equation for elastic potential energy. Equation for elastic force.
What is EPE=1/2kx^2? What is F = kx?
400
The form of energy often referred to as solar energy or light energy.
What is electromagnetic energy?
400
This form of energy is transferred by mechanical waves. The particles that make up a substance vibrate in a highly organized manner and transfer energy through the substance.
What is sound energy?
400
Something that quantifies the amount of energy in each form for a specific portion of an energy chain.
What is an energy diagram?
400
The rate at which energy is transferred.
What is power?
400
Determine how much energy a spring with a spring constant of 15 N/m stores if it is stretched 1.6 m.
What is 19 J?
500
This type of energy results when a material is deformed by stretching or compressing and returns to its original shape.
What is elastic potential energy?
500
An 725 kg automobile has a kinetic energy of 3.02 × 105 J as it travels along a highway. What is the car’s speed?
What is 28.9 m/s?
