Forms of Energy © The Science Duo

Energy • The ability to do work or cause change • The majority of energy on Earth originates from the Sun • There are many different forms of energy MR CENTS Strategy M = Mechanical R = Radiant C = Chemical E = Electrical N = Nuclear T = Thermal S = Sound

Mechanical Energy • The energy in moving objects • Energy of motion or position • Can be potential energy or kinetic energy Examples of Mechanical Energy Spinning Gears Windmill Riding a bicycle

Radiant Energy • Energy of light; also referred to as light energy or electromagnetic energy • Travels in waves • Travels in a straight path from one place to another Examples of Radiant Energy Television Traffic Lights Cell Phone

Chemical Energy • Energy stored in the bonds of molecules • Involved when chemical reactions take place • A form of potential energy Examples of Chemical Energy Food Coal Battery

Electrical Energy • The energy of moving electrons or electric charges • Electricity is used by many different objects in our daily lives • Electricity was first used in homes in the late 1800 s Examples of Electrical Energy Lamp Electrical Outlet Charger

Nuclear Energy • The energy locked in the nucleus of an atom • Nuclear Fission – the process of splitting an atom • Nuclear Fusion – two or more atoms violently joined together to make a larger atom Examples of Nuclear Energy Sun (Stars) Power Plant Atomic Bomb

Thermal Energy • The energy of heat • Particles of hot objects move faster than the particles of cooler objects • Hot = more thermal energy; Cold = less thermal energy Examples of Thermal Energy Iron Toaster Fire

Sound Energy • The energy from vibrations in matter • Sound can travel through solids, liquids, and gases • Sound must have matter to travel through Examples of Sound Energy Bullhorn Alarm Clock Radio
