Energy and 10 different types

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.

Water that is behind a dam.

A raised weight

Due to gravity

Associated with Gravitational Field

G= MGH

Natural force

Mechanical Energy

Types of mechanical energy

rotational kinetics

Transnational kinetics

Due to motion

example-ideal simple pendulum

K.E.= 1/2 mv2 + mgh

Sum of kinetic energy and potential energy

Chemical Energy

petroleum

wood

coal

S.I. Unit- joule

C.E=6CO 2 + 6H 2 O – C 6 H 12 O6+ 6O2

energy stored in chemicals

Light Energy

Electromagnetic radiation

light bulbs

Sunlight

Energy of Light = (6.626 × 10-31 × c) / w(m)

travels in straight lines

Kinetic Energy

energy of motion.

airplane

A river flowing at a certain speed

K.E= [Mass × Velocity2] × 2-1

easiest to observe

Nuclear Energy

Energy released during nuclear fission

Example= nuclear fission

N.E= mc2

Splitting atoms in a reactor to heat

Potential Energy

Energy stored in an object

Example

Stretching a rubber band

pendulum

P.E= mgh

Dimensional formula

M1L2T-2

Energy possessed by a body

Sound energy

Musical instruments

Gulping Water

Belching

longitudinal Waves

S.E= Sound power/ Area

S.I unit= Watt

Due to vibration

ENERGY

Dimension formula

[E] = [ML2T-2]

Examples

releasing the arrow from the bow

shooting a rubber band

S.I. Unit= Joule

Quantitative property

Work

Magnetic Energy

magnetic field

Magnitude and direction at the same

Example-generator

B = μ0/2πr
