Work and Energy (Types of Energy)
Transcript of Work and Energy (Types of Energy)
In base SI units:
What is Energy?
The Energy of Motion
Potential Energy (5 Types)
But... What is Work?
Energy that is stored.
is the ability
to do work.
1 J = 1 N·m = 1 kg·m /s
1818 - 1889
Energy can be broken down into 2 categories...
Types of Energy
These all have to do with the energy of motion.
These all have to do with some type of stored energy.
Mechanical Kinetic Energy (MKE)
The energy of any normal moving object.
The energy of vibrating atoms and molecules.
It’s like mechanical kinetic energy, but on the VERY small scale.
Radiant (Light) Energy
The energy of light, or any other electromagnetic radiation (such as x-rays or microwaves).
The vibrations of mediums that transfer sounds.
Gravitational Potential Energy (GPE)
The energy a high up object has.
It gives off this energy by moving down.
Electrical Potential Energy
have because they want to move towards (or away from) other charged particles.
This is a lot like gravity / GPE!
Elastic Potential Energy
The energy stored in any object that is
and wants to return to its original shape.
Chemical Potential Energy
The energy stored in chemical bonds.
As these bonds are broken (or rearranged) the energy is released.
Nuclear Potential Energy
Very similar to chemical energy.
Here, the atomic nucleus within the atom is changed rather than rearranging atoms within molecules.
