There's no reason why almost any process that does work in air on Earth
can't also be done in space in vacuum. One example: The operation of
inserting an artificial satellite into orbit certainly involves a lot of forces
acting through a lot of distances, to get the satellite moving just right.
Any time you see a rocket engine burning with fire coming out the end,
the force of the engine is acting on the space vehicle as it moves through
some distance. And (force) x (distance) = Work .

What is present when work is done?
In physics work is dome when a force acts on a body and the body moves in the direction of the force.
When can you say that work is done on an object?
when a force acts to move an object,we say that work was done on the object
What is the definition of work done?
Physics definition of work: (force applied ) multiplied by (distance through which the force acts).
Work done by a variable force?
A variable force is that force whose magnitude, direction both change as it acts.
Write the formula for the work done on a body when a force acts on the body in the direction of its displacement?
WORK = FORCE x DISPLACEMENT
How much work is done when a vertical force acts on an object moving horizontally?
as work done is dot product of force and displacement so cos(90)=0;therfore work done is zero
How much work is done when a vertical force acts on an object horizontally?
It depends on the magnitude of the force and the mass of the object
How much work is done when using a force of 10 n?
The work is(10) times (the distance through which the force acts, in meters) joules.
Work is done when?
work= force × distance so if an object moves 4metres, and the force to move it is 2N, (Newtons) the work done would be 4 × 2 = 8Joules (Work is measured in Joules) In other words, work is done when an object moves a certain distance when a certain amount of force is applied to it.
How much work is done when a vertical force acts on a moving object horizontally?
It depends on the magnitude of the force and the mass of the object
How much work is done when vertical force acts on an object moving horizontally?
It depends on the magnitude of the force and the mass of the object
Define 1J of work?
One joule is the amount of ''work'' done when a force of 1N acts over 1m By The Aalap
