So it doesnt fall in, theres no way for a circle to fall into the hole, whereas a square manhole, when tilted at the right angle, could fall in and hurt the workers underneath.
In short Pure physics is the theoretical knowledge of concepts of physics, while applied physics is the knowledge of techniques that help to apply this theoretical knowledge to practical problems.
I am currently doing Applied physics in College. In my particular college, applied physics is coursework based, there are no exams whereas for Physics, there are.Applied physics, at my college, involves a lot of practical work and stems into fields of Biology and Chemistry alongside Physics, focusing on all three for a first year during a National Diploma course, and only physics during the second year.Generally, Applied Physics refers to the use of physics; how it is used in various fields eg engineering. Whereas, Physics or sometimes called Pure Physics can be more theoretical, new research, new areas to explore.The work being done at CERN in Europe, the large hadron collider where atomic particles are being collided would be Physics. The two fields will largely overlap and the discoveries made in Physics will leak into Applied Physics.
In physics, work is defined as the force applied to an object over a distance. To make work easier, you can either increase the force applied or shorten the distance over which the force is applied. Using tools or machines can also help by amplifying the force applied or making it more efficient.
Work is zero in physics when there is no displacement of an object, meaning that no force is applied to move the object over a distance.
Work is done when a force is applied to an object and causes it to move in the direction of the force. Mathematically, work is calculated as the force applied multiplied by the distance over which the force is applied. Work is a scalar quantity measured in joules (J).
because for any person to get inside a manhole, you would think it was shaped like a round circle.

There are various reasons that manholes are shaped like a circle. For example, it is much easier to dig a circular hole.
Japanese Journal of Applied Physics was created in 1962.
