W=Fd and F=ma W is work (energy), F is force, d is distance, m is mass, and a is acceleration.
plug in to get W=mad so ad=W/m
(vf^2)=(vi^2) + 2ad where vf and vi are velocity final and initial respectively.
Assume vi=o so (vf^s)=2ad
rearrange so ad=(vf^2)/2
Plug in again to get W=m[(vf^2)/2] which is kinetic energy.

What is the equation for power in a way that shows what work equals?
Work is basically a type of energy. Power is equal to energy / time; therefore, energy (or work) = power x time.
What is the equation used to work out energy efficiency?
a+b=c/3
What is energy balanced?
Energy balance can be described by this equation : Energy intake = internal heat produced + external work + energy stored.
How does movement use energy?
Movement itself does not use energy. However if there is friction then energy will be lost according to the equation, Work = Force x Distance. Also, there is energy associated with movement according to the equation, Ek=½mass x (velocity)²
What is the importance of work-energy theorem?
it is a modified version of one of the newtons equation , newton equation cannot define the relation between work and enrgy thats why we generate the relation for work enrgy theorem

What is equation to calculate potential energy?
work=force x output

What is Einstein's photoelectric equation?
E(photon energy)=K.E+Work Function
What is the purpose of th gibbs free energy equation you don't need to know the equation itself?
The purpose is to determine the available energy. Some of the energy in any system is useless - can't be converted into useful work.

What is WORK defined in science?
Work is the transfer of energy, measured in Joules. so if you lift a book in the air you have transferred energy to it (your kinetic energy to its gravitational energy) and so you have done WORK The equation to calculate mechanical work is: WD = Force x distance For electrical work it is WD = V I t
How does power relate to work in physics?
Work gives us energy in Joules, which can be subbed back into the first equation to solve for power.
How is the term 'energy' defined in physics?
Energy is the capacity of a body to do work. Mass and energy are directly proportional according to Einstein's famous equation, E=mc^2.
What are the rewards that women derive from work?
none
