Write true or false for each statement (a) A man going up has potential energy and kinetic energy both.(b) A gum bottle lying on a table has no energy.(c) In an electric fan, electrical energy changes into the mechanical energy.(d) Potential energy changes into kinetic energy when it is put to use.(e) One form of energy cannot be converted into another form.(f) There is always some loss of energy in conversion from one form of energy to another form, so the total energy is not conserved.(g) The energy of flowing water can be converted into electric energy (electricity).

Answer»

(a) True

(b) False

(d) True

(e) False.

(f) False

Correct — There is always some loss of energy in conversion from one form of energy to the other form, so the total energy is conserved.

(g) True
