Q.11. Define one joule.

Hi Khushboo dear, definition for joule
One joule of work is said to be done when a force of 1 newton displaces a body through a distance of 1 metre in the direction of force
Reason for such a definition is right from the following formula for work done
W = F s cos @
W becomes 1 when F = 1, s = 1 and cos @ = 1 i.e @ = 0
Hence the definition

  • 2
  1. the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one metre in the direction of action of the force.
