Study Notes
Work, Energy, and Power
- The formula for work done is W = F × d, where W is work, F is force, and d is displacement.
- Units of energy include Joules (J) and Kilojoules (kJ).
- Work and energy are equivalent, as work done on an object increases its energy.
- The amount of work done on an object is represented by the symbol W and is measured in Joules (J).
- The relationship between work and kinetic energy is described by the work-energy theorem, which states that the net work done on an object is equal to its change in kinetic energy.
- The unit of power is the Watt (W), where 1 Watt is equal to 1 Joule per second (1 W = 1 J/s).
