Force,Work,Power,Energy

Energy

how to measure energy?

Potenital= MxGxH

What types of energy are there?

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

What is energy?

energy cannot be distroy it can only be changed

energy is the capacity of work done

Power

what is the SI unit for Power?

Watt (W)

How to measure power?

Power=energy/time

what is power?

power is the rate of doing work/ transfer energy Subtopic

Work Done

how to measure work done?

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

What is work done?

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

what is the SI unit for work done?

Joule

Force

force has a SI unit

how do we measure force?

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

Spring Balance

weighting scale

What is force?

force is a push/pull

force can cause effects

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