Energy Types

Kinetic: Energy of motion (KE = ½mv²)

Potential: Stored energy due to position (PE = mgh)

Thermal: Energy from temperature change (Q = mcΔT)

Work: Energy transferred by force (W = F×d)

Energy Units

Joule (J): SI unit of energy

kWh: Kilowatt-hour (3.6 MJ)

Calorie: Energy to heat 1g water by 1°C

BTU: British Thermal Unit (≈1055 J)
