Things to know pt. 1
All energy is transferred between objects when work is done
Relationship between work,energy,and power
work is when a force moves an object, power is the rate at which work is done and energy is the ability to do work.
The formula and unit to calculate power
Power = Energy transferred / Time
Formula= Watts or W
