Energy and 10 different types

Heat energy involves the transfer of thermal energy through conduction, convection, and radiation, leading to a rise in temperature. Light energy, a form of electromagnetic radiation, travels in straight lines and can be observed in sources like light bulbs and sunlight.

Heat Energy

Types of H.E
Radiation
Convection
conduction
Rise in Temperature
Transfer of thermal energy
Q=M.C.(Tf-Ti)
Movement of atoms and molecules

Gravitational Energy

Examples of G.E.

A raised weight
Due to gravity
Associated with Gravitational Field
G= MGH
Natural force

Mechanical Energy

Types of mechanical energy
