applied physics vs physics

Imagine the following situation. A heavy crate is resting on the floor in a warehouse. You push it horizontally with a steady force, but it does not move. That is because the force that you apply is balanced by a frictional force exerted horizontally on the bottom of the crate by the floo..

When we apply the force the door turns on its hinges. Thus a turning effect is produced when we try to open the door. Have you ever tried to do so by applying the force near the hinge? In the first case, we are able to open the door with ease. In the second case, we have to ..

Introduction - Physical world and Measurement - Physics is sometimes called as 'science of measurement'. The acceleration produced by a force for the motion of a body can be known by measuring the magnitude of applied force and mass of the body. Similarly, the distance..

The effort is the force applied to the machin..

Moseley's Law - Moseley had done experiments on the characteristic X-rays and this led to the development of the concept of atomic number. The periodic table was made according to the atomic weight in earlier days. But some anomalies were found in such an arrangement. Moseley measured the frequenci..

The rate of change of momentum of a body is proportional to the applied force and takes place in the direction in which the force is applied..

These are caused by external conditions (wind, temperature, etc.,). These errors can be prevented by applying suitable correction..

Laws of Radioactive Disintegration - The number of atoms disintegrated per second at any instant is directly proportional to the number of radioactive atoms actually present in the sample at that instant. If N o be the total number of atoms at t = 0, N be the total number of atoms left in the sampl..

Eddy currents can brake the motion of the train too. A metal drum is attached to the train. To apply brakes a strong magnetic field is applied across the drum. The eddy currents set up in the drum in a direction as to oppose the change in the magnetic flux that is, it opposes t..

It is easier to open the door by applying force near the outer edge away from the hinge..
