Question

Give examples of the following transformations:-

I)Electricity energy to heat energy.
II)Kinetic energy to potential energy.

Answer 1

1. Toaster

2.throwing a stone vertically up with some velocity

Answer 2

I) electrical energy is in the form of kinetic energy by moving of a charge particles (i.e electrons)in the conductor when the speed of electrons increase in the conductor the electrons collide with each other and heat is produce due to the conversion of kinetic energy of the electron.
II) potential energy is stored due to position of an object example object is placed at height 'h'energy is stored in the form of potential energy (mgh) when a stone is throw Vertically upward after reaching certain height the kinetic energy is converted into potential energy and stone starts free falling
