Chapter Work

Scientific View of Work:

1. Introduction:

   • Understanding work and its definition from a scientific perspective.

2. Examples:

   • Pushing a pebble: Exerting force causes displacement, hence work is done.
   • Pulling a trolley: Force applied causes displacement, fulfilling conditions for work.
   • Lifting a book: Force applied causes upward displacement, meeting criteria for work.

3. Conditions for Work:

   • Two conditions must be satisfied for work to be done:
     • Force acting on an object.
     • Object must be displaced.
   • If either condition is not met, work is not considered to be done.

4. Application to Situations:

   • Examples illustrate how work is defined in science.
   • Each scenario involves force and displacement, fulfilling conditions for work.

5. Evaluation:

   • Analyzing whether work is done when a bullock pulls a cart.
   • Cart movement indicates force and displacement, meeting criteria for work.
