Force Causes movement of an object, whereas Power is the work done on an object in a given amount of time.
<h3>What is Force?</h3>
In science, force is defined as the push or pull on an object that has mass which causes it to move (to accelerate).
The SI unit of force is newton, N. and its given as
Force(F)= mass × acceleration
Example of forces include
- Gravitational force
- Electric force
- Magnetic force
- Nuclear force
- Frictional force
<h3>What is Power?</h3>
Power is the rate at which work is being done on an object. It is also the rate at which energy is transferred from one place to another.
Power is the amount of work completed or energy released per unit time.
The SI unit for power is the watt (W), and is given as
Power = Work / time
P = W / t

The number of btus that are needed to cool lucia’s apartment is 20,400 btus.
<h3>BTUs needed</h3>
First step
Left side=12×10×20
Left side=2400 cubic feet
Middle =16×10×(20-9)
Middle =16×10×11
Middle =1,760 cubic feet
Right side=20×10×20
Right side= 4000 cubic feet
Second step
BTUs:
BTUs=(2400+1760+4000)×2.5
BTUs=8160×2.5
BTUs=20,400 Btus
Therefore the number of btus that are needed to cool lucia’s apartment is 20,400 btus.
