Topics in Work and Energy
1
Work
- 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
