Write an expression for the work done when a force is acting on an object in the direction of its displacement.

Write an expression for the work done when a force is acting on an object in the direction of its displacment.

Write an expression for the work done when a force is action on an object in the direction of its displacement?

Answer the following questions: Derive the expression for the work done when the displacement is in the direction of the force.

How is work done by a force measured when the force : is in the direction of displacement.

What is the work done when the force on the object is zero?

A Force F acts on a body and displaces it by a distance S in direction at an angle theta with the direction of force ,(a) Write the expression for the work done by the force,(b)What should be the angle between the force and displacement so that the work done is (i)zero ,(ii)Maximum ?

The work done by a force is said to be …….when the applied force does not produce displacement.

1 joule of work is said to be done when a force of 1 N acting on an object moves it by 1 metre in the direction of force.
