We know that the vehicle
needs a key to start the engine so that the transformation of energy will
happen according to Thermodynamics. The gas will be converted to be the source
of energy. When it was started to push accelerate it will move forward and makes
motion, under the branch of Physics which is Mechanics.
If you have seen an electric-mosquito killer it produces electric
charges that make the mosquito kill which is under the Physics; Electromagnetism.
The electric current moves to metal where the insects can be trap and kill
easily. It also emits heat because of to much release of energy.
Can you here sound from our different
gadgets? Our speaker has a electromagnetism principle, because it uses energy
to operate. It produces vibrations, sounds, and ultrasound that we can hear. Under
the definition of the Acoustic, one of the branch of Physics.
