name the 5 types of energy
thermal, radiant, chemical, mechanical and electrical
explain thermal energy
energy that comes from the random motion of particles hat make up a substance. temperature increase, particles move faster
if we had 2 beakers of water, each with 100ml of water, the ——- would have ———–
warmer beaker, more thermal energy
if we had two beakers of water at the same temperature, the beakers with —- would have —-
more water, more thermal energy
explain radiant energy
energy is transported by electromagnetic waves, different type of waves carry different amounts of energy
what is the visible light spectrum (check notes for pictures)
the only very small portion of the entire electromagnetic spectrum. IT ranges from just after ultra violet light to right before infrared light
explain chemical energy
energy that is stored in the bonds of a substance. The bons need to be broken and rearranged in order to release the energy
name examples for chemical energy ( check notes )
photosynthesis is when plants us energy from sun to make their own food, use the wood to burn and generate thermal energy solar energy-tree photosynthesis-burning wood- fire
explain mechanical energy
energy that results from the motion of an object. it can also depend on the distance from the ground. ( physical change)
explain electrical energy
occurs with the movement of electrons through a closed circuit. For electrons to travel, metal has to touch metal within circuit.
example electrical energy
Lightning is a natural phenomenon that carries an electric current. Any appliances plugged into an outlet uses electrical energy. Then it converted into its useful form.

explain energy transfer AND transformation
energy cannot be created or destroyed, is can be transferred of transformed
explain TRANSFORMATION
involves changing of energy from one form to another
example of TRANSFORMATION
burning a log, chemical energy stored in woo dis transformed into thermal and radiant energy
explain TRANSFER
involves the movement of energy from one place to another, type of energy stays the same
example of TRANSFER
kick a soccer ball, mechanical energy is being transferred from your leg to the ball
