Question

Q - 1 Write an expression for the work done when a force is acting on an object in the direction of its displacement.

Q - 2 Define 1J of work.​

Answer 1

Answer:

1.Write an expression for the work done when a force is acting on an object in the direction of its displacement. If F is the constant force acting in the direction of displacement s, then work done by the force, i.e., W=F×s=Fs

2.Joule is amount of work done when a force of 1 Newton displaces a body through a distance of 1m in the direction of the force applied.

Answer 2

Explanation:

Write an expression for the work done when a force is acting on an object in the direction of its displacement. If F is the constant force acting in the direction of displacement s, then work done by the force, i.e., W=F×s=Fs.
