- kinetic energy, T = 1/2 mv^2

multiplying and dividing m, we get,

T = (1/2 m^2.v^2)/m

= (p^2)/2m ( p= mv)

- Unit of power is watt, which is

watt = joule/second

Unit of Plank constant is joule.second

so, watt.(second)^2 = (joule/second).

(second)^2 = joule.second

which is, in fact, the unit of Plank’s constant. - <ΨIΨ> = 1 is the property of

orthonormality. For example, in cartesian

co-ordinate, i.i = 1

<ΨIF> = 0 is the property of

orthogonality, where Ψ and F are two wave

functions. And they are orthogonal.

For instance, in cartesian co-ordinates, i.j =

0 - Schrödinger’s cat experiment uses

quantum superposition as its basis idea.

The fact that the cat can be both alive and

dead at the same time is an analogy of

quantum superposition. - Quantum computers use qubits the

same way our computers use binary

numbers 0 and 1. But quantum computers

use the principle of quantum superposition.

Therefore, 0 and 1 exist in a superposed

state.
