About Energy Conversion
Energy is the capacity to do work. It exists in many forms: kinetic, potential, thermal, electrical, and more. Understanding energy units is essential across physics, engineering, and everyday applications.
Forms of Energy
- Mechanical Energy: Joules, foot-pounds for motion and position
- Thermal Energy: Calories, BTU for heat content
- Electrical Energy: Watt-hours, kWh for electricity consumption
- Chemical Energy: Calories in food, BTU in fuel
Energy in Daily Life
- Food calorie = 1 kilocalorie = 4,184 joules
- Average home uses 10,000-15,000 kWh per year
- Gasoline: ~34 MJ per liter of chemical energy
- Human body at rest: ~100 watts of power
Energy Conservation
The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another. This fundamental principle governs all physical processes and energy conversions.
