The key difference between force and work lies in their definitions and the physical quantities they represent:

• Force:

  • Definition: Force is a vector quantity that represents the interaction between two objects. It is a push or pull exerted on an object that can cause it to accelerate, change its shape, or undergo deformation.
  • Units: The standard unit of force in the International System of Units (SI) is the Newton (N).
  • Symbol: Force is often represented by the symbol "F."
  • Example: When you push a door to open it, you apply a force to the door.

• Work:

  • Definition: Work is the product of force and the displacement of an object in the direction of the force. It is a measure of the energy transfer that occurs when a force causes an object to move a certain distance.
  • Units: The standard unit of work in the International System of Units (SI) is the Joule (J).
  • Symbol: Work is often represented by the symbol "W."
  • Example: Lifting a book against the force of gravity involves doing work.
