Answer:

This is personal question, very interesting! Depend on who is the person, where the person is working at, how old is that person - we can have various answers.

Personally, I think first about that human and other animals needs energy to survive, that means we need to eat, to drink; The plants need energy to survive too - that is the energy from the Sun.

Secondly, the human being needs such types of energy as electricity, wind, solar energy, etc. in oder to live. Even the acient people learnt to use solar and wind and water - natural energy from the nature.

Thirdly, the human being needs spiritual energy to have a good life.

Another specific terms of energy related to physics and chemistry, and even biology - actually are not in my mind in everyday life.

A rod made from insulating material carries a net charge, while a copper sphere is neutral. The rod and the sphere do not touch.
navik [9.2K]
<span>As the charged insulating rod approaches the sphere (not in contact), free electrons in the sphere move. If the rod is negatively charged, free electrons move to the side of the sphere opposite the side with the rod. If the rod is positively charged, the free electron moves to the side of the sphere with the rod. In either case, the region of the sphere near the rod acquires a charge with the sign opposite to that on the rod.

a. Since opposedly charged objects always attract each other, the rod and ball always experience mutual attractive forces.

b. Since the side of the sphere near the bar always has the opposite charge to the charge of the rod, the rod and the sphere always attract each other. <span>They do not repel each other.</span></span>

What it means to say that energy is conserved as a ball fall towards ground
stiv31 [10]
Mechanical energy = Potential Energy + Kinetic Energy

if there is no friction, M.E. is conserved
as a ball falls, it is losing height. (P.E.=mgh , therefore P.E. will decrease)

the potential energy is transformed into kinetic energy which equals 1/2MV^2.

the increase in K.E. equals the decrease in P.E.

and the sum of both equals M.E.

thus mechanical energy is conserved.

hope this helps you.
