Are these work and energy definitions correct?

[Daniel2244]

Are the following definitions correct?

• Work done as energy transferred

The energy transferred when the forces between two objects interact

• Work done by a force

Work done = force x distance moved in the direction of force applied (W=F*Δs)

• Work done by a gas

Work done = pressure x change in volume of gas (W=p*ΔV)

Did you just... I mean, you answered the 2nd and the 3rd question yourself.

 

[Sk Sohel Mistry]

When a force is applied to a body and the body is displaced from its original position then work is done.
