Weight: The force with which an object is attracted towards the earth is the weight of that object.
It is written as W = m × g.
The SI unit of weight is newton (N).
Work: Work done in moving a body is equal to the product of force exerted on the body and the distance moved by the body in the direction of force.
It is written as W = Force × Distance.
The SI unit of work is newton metre (N m) or joule (J).

- an object thrown at a certain angle to the ground moves in a second path and falls back to the ground the initial and the final point of the path of the object lies on the same horizontal line what is the work done by the force of gravity on the object?
- A car of mass 2 kg is moving with speed of 10m/s. Calculate work done to stop it ?
- painting is work or not
- Work done does not depend on the distance travelled. Give reason.
- When work is said to be done?
- How do you know that some entity is a form of energy ?
- Person A move from ground to third floor of his house through lift and person B do the same job with staircase who has done more job give reason
- in displacing a body 5 metre by a force of 50 Newton the work done is 125 joule find out the angle between the direction of force and displacement
- What is work done?
