Force,Work,Power,Energy

force can cause effects

it can change its shape/size, speed, direction and can start/stop a object

What is force?

force is a push/pull

how do we measure force?

we can measure force by using a weighting scale or a spring balance

force has a SI unit

what is the SI unit for work done?

Joule

What is work done?

work done cane only happen when the force and the object are moving in the same direction

how to measure work done?

Force = WxD ((weigth x 10)N x Distance Moved = Joule

what is power?

power is the rate of doing work/ transfer energy
Subtopic

How to measure power?

Power=energy/time

what is the SI unit for Power?

Watt (W)

What is energy?

energy is the capacity of work done

energy cannot be distroy it can only be changed

What types of energy are there?

there are eight types of energy kinetic, potential, Nuclear,Sound,Light,Electrical,Chemical and Heat

how to measure energy?

Potenital= MxGxH
