work
work is defined as the dot product of force and displacement in the direction of force applied
1.work is scalar quantity that has only magnitude no direction.
2.it is a dot product b/w force and displacement.
3.the S.I. unit of work is joule.
energy
energy is capacity of doing work the S.I. of energy is joule.
There are 2 types of energy in this chapter
1.kinetic
2.potential
the energy possed by a body due to its change in position or shape is called potential energy.
the energy posses by its virtue of its motion is kinetic energy.

if any query to u I will help u
Ok thanks
The combining power or capacity of an elements is known as valacy
1.valancy is determine whether it donate or gain
2.if it donate the electron it's valacy will be positive
3.if it gain the electron it's valacy will be negative
Okay
Now I hv understood
Thanks bro
:-) it's my pleasure

work= if we aplied any external force to any object that is called work and its unit is joule .
work=force × displacement= newton-meter
and according to work energy theorem energy can neither created nor be distroyed it will be transfered one form to another form .
as a example - we know a electric fan work on a work energy theorem we use there electric energy to start fan and after that electric energy is converted in mechanical energy.
