In physics, "work" is when a force applied to an object moves the object in the same direction as the force. If someone pushes against a wall, no work is done on the wall because it does not move. However, depressing a letter on a computer keyboard requires work.
That means that if the force you're talking about is horizontal as well (or has a horizontal component), then that force has indeed done work on the car.
Elizabel Uayan yes both will be work done by you, as when you lift the pen you do a work against the gravitational field and hence it's potential energy increase by (mg)(h) i.e force * distance which is nothing but the work done. But the net work done on the pen i.e work done(by you) + work done(by gravity) = 0 (i.e change in kinetic energy) . Work done by you and total work done on the object are two different things

This is the science of manifestation. Think of this as a quantum explanation of life. We put out energy. Will and drive implies the Force of energy 😉💗
Nice
A car travelling on a horizontal plane is work done or not
Vijay Narayan Mishra that depends on the force you are talking about.
The formula for work done by force F is:
W= F*D(parallel)
Where D is the displacement parallel to F.
That means that if the force you're talking about is horizontal as well (or has a horizontal component), then that force has indeed done work on the car.
if a pen lifted from the floor to the top shelf , is work or not?
and also a man lifted a pen placed on the table, is work or not?

you are gay. that is work
thanks
