What is the relation between physics and technology?



Broadly speaking, physics and technology both constitute science. Physics is the heart and technology is the body of science. The application of the principles of physics for practiced purposes becomes technology, e.g.,(i) Aeroplanes fly on the basis of Bernoulli’s theorem.

(ii) Rocket propulsion is based on Newton’s second
and third laws of motion.
(iii) Generation of power from nuclear reactor is based on the phenomena of controlled nuclear fission.
(iv) Lasers are based on the population inversion of
electrons and so on.
Thus, we can say that to some extent science and technology is applied physics.
