Mechanical Work:
Applying a force over a distance, AKA moving something.
The magnitude of work is:
Work = force * distance

Unit of Work:
Joule
1 J = 1 N*m

Conservation of Energy:
Energy cannot be destroyed or created

Energy:
The ability to do work
OR
Generate heat 🙁

Mechanical Energy:
The energy is due to the motion of an object.

System:
A portion of the universe we care about
All forces in the system are INTERNAL

Conservative Forces:
Conserve means conserve MECHANICAL energy.
Forces where the path of the object doesn’t matter, just the beginning and the end.

Power:
Rate of change of energy, AKA how much energy is being put INTO a system over time.

Unit:
Watt (W) = J/s

Good conversions to know:
P = E/t
E = P*t
E/t = P
