The question is, what is energy, what is work, and list some examples of each.
00:07
So first of all, energy is defined as the capacity to do work or produce heat.
00:28
And that can be found on page 15 and page 368.
00:35
Some examples of energy include kinetic energy, which is the energy of motion.
00:55
This can also be found on page 368.
00:59
Another example would include potential energy, which is the energy due to position.
01:18
This can also be found on page 368.
01:26
There is also thermal energy, which is the energy associated with temperature and all of these.
01:55
And the last example i have is chemical energy.
02:05
And i'm just going to read this one off.
02:10
I'll put some bullets here.
02:11
It's a pretty long definition.
02:15
So this is the energy associated with the relative positions that's important of the electrons and the nuclei in atoms and molecules.
02:40
Okay.
02:55
And the second part of the question asks us, what is work? and to list some examples of that.
03:02
So work is defined as force acting over a distance.
03:25
It's also found on page 368.
03:30
And some examples of that are pushing a box across the floor.
03:38
You push a box across the floor.
03:49
You are doing work.
03:51
You're providing the force and it's moving across the floor...
