Applied Physics

Applied physics, also known as engineering physics, is the connecting study between physics as a pure science, mathematics and engineering. Fundamental physics is combined with problem solving and engineering skills to brooded applications. This interdisciplinary knowledge is designed for continuous innovations occurring with technology.

The term “applied” is distinguished from “pure” by the motivation and nature of the research. Applied physicists conduct research to develop new technologies or solve engineering problems by the application of basic scientific principles; whereas physicists conduct research to prove new theories and discover new abstract concepts. For example, Einstein’s special theory of relativity was discovered by pure physicists. The design of fiber optic technology is an applied physics discovery.

The field of applied physics has a wide variety of research areas. Astronomy, Astrophysics and Relativity and Condensed Matter Physics and Optics are just a few examples of the vast range of research areas. These research areas are concerned with the potential for new technology or practical applications.

Applied physics can be offered at the levels of B. Tech, B. Sc., M. Sc. And Ph. D. The core curriculum is advanced mathematics, physics, chemistry and biology. While studying applied physics it is possibly to specialize in many different areas including fluid dynamics, quantum physics, bioengineering, plasma physics to name a few.

Gravitational force

A 21.0 kg sphere is at the origin and a 5.00 kg sphere is at (x,y) = (20cm,0cm). At what point can you place a small mass, such that the net gravitational force on it, due to the sphere's is zero?

Momentum, Impulse, and Collisions

Starting at t= 0, a horizontal net force F = (0.280 N/s)ti + (-0.450 N/s^2)t^2j is applied to a box that has an initial momentum p= (-3.00 kg.m/s)i + (4.00 kg.m/s)j. What is the momentum of the box at t= 2.00s?


The coefficients of static and kinetic frictions for plastic on wood are 0.50 and 0.40, respectively. How much horizontal force would you need to apply to a 3.0 N plastic calculator to start it moving from rest?

Air Pressure at a Point on an Airplane's Wing

Consider an airplane flying with a velocity of 60 m/s at a standard altitude of 3km. At this point of the wing the airflow is velocity is 70 m/s. Calculate the pressure at this point. Assume incompressible flow.


Two blocks are in contact on a frictionless table. A horizontal force F is applied to M1, as shown. If M1 = 1.93 kg, M2 = 3.30 kg, and F = 5.90 N. If instead an equal but oppositely directed force is applied to M2 rather than M1, find the size of the contact force between the two blocks. Please see the attachment for diagr
