  • Work is done when a force applied on an object causes displacement of the object
  • Work = Force × Displacement (when force and displacement are in same direction)
  • When force is at an angle θ to displacement: W = F × s × cos θ
2

Energy and Its Forms

  • Energy is the capacity of a body to perform work
  • Energy has the same unit as work - Joule (J) in SI system
  • Energy exists in various forms: mechanical, heat, light, sound, chemical, nuclear, solar
3

Kinetic Energy

  • Kinetic energy is the energy possessed by an object due to its motion
  • Moving objects can do work when they strike stationary objects
  • Kinetic energy depends on mass and velocity of the object
4

Potential Energy

  • Potential energy is stored energy due to position or state of an object
  • Gravitational potential energy depends on height above reference level
  • PE is directly proportional to mass, height, and acceleration due to gravity
