Contact force is present only during the “contact”. It does not remain in/on the body when the “contact” is over. Example: When you press your hand against your desk, you feel the repulsion of the electrons in the atoms of your hand against the electrons in the atoms of the desk....
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.

Emmy Noether discovered a deep connection between the existence of continuous symmetries and conservation laws in 1918. Conservation of energy, for example, is intrinsically linked to time-translation symmetry and conservation of momentum is linked to spatial-translation symmetry. ...
In other words, this collision acts like a measurement of the position of the alpha-particle. However, the more accurately the position is determined (i.e., the more strongly the alpha particle is localized), the less determined is its momentum and, so, subsequently, the alpha-particle ...

We show that attempts to modify the force on a magnetic dipole by introducing either hidden momentum or internal forces are not correct. The standard textbook result ${\\bf F=abla(\\bmu\\cdot B)}$ is correct even in the presence of time dependent electromagnetic fields. Using this expressi...
The center of a black hole, where all of its mass is concentrated, is called the singularity. Gravitational Constant The gravitational constant (G) is a fundamental constant in physics that describes the strength of the gravitational force between two objects. It has a value of approximately ...
