Work (W) is the product of force (F) and distance (D). So:
W=F x D
This applies regardless of the mass of the body and assumes that no other forces, like friction, are involved.

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.
Differentiate batween the work done on the body and work done by the body?
note: Work done is = force applied to a body * time taken by the body When we apply a force on to an object such that the object displaced in the direction of force, then some unit of work is done on the body. When a body sets another body into motion by applying a force, in unit time, that body is considered as it had done a unit of work
Why does the body need to generate force?
To do work.
How force and energy are related?
Energy is defined as the ability to do work. Work is defined as the force required to displace a body. So that means to apply the approximate amount of force to displace the body you have to use some energy. OR To displace a body one must convert its potential energy to mechanical energy by means of force.
Is it possible workdone is zero although body is moving?
Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.

What is defined work?
if the force applied on a body makes a body move that is there is a displacement of the point of application of force in the direction of force then work is said to be done by the body
Which force do not work on the body on which it acts?
frictional force
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
What is work in physics?
in physics work work=force *distance the distance covered by body by any force is called work.

What is the work done when a force will be applied on body in absence of any other force?
infinite
State the conditions needed for a body to have nonuniform velocity?
One condition, the net force acting on the body should not be zero.
Is it possible workdone is zero although body is moving?
Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied.

Work is the product of force and an object's what?
Yes. A force acting on a body in the direction of its motion does work. The formula for work is W = F x d, where force(F) is in Newtons, distance(d) is in meters, and work(W) is in Newton*meters(N*m), or Joules(J). (1N*m = 1J) A force acting on a body in the opposite direction to its motion does "negative work". It causes the moving body to slow down, the moving body loses kinetic energy, and that energy is absorbed by the source of the force. Mathematically, the force and the distance it moves through have opposite directions, so the product of (force) x (distance) is a negative number: negative work.
