Newtons laws of motion
Briefly illustrate all the Newton s laws of motion?
Expert
The Newton's laws of motion are as follows:
a) The body at rest will remain at rest and the body in motion will always remain in motion, until and unless acted on by the external force. (That is, Law of inertia)
b) The rate of change of momentum of a body is proportional to the resulting force acting on the body in similar direction as its motion. (That is, F = ma)
c) For all action there is an equal and opposite reaction.
Kirchhoff's law of radiation (G.R. Kirchhoff): The emissivity of a body is equivalent to its absorbptance at similar temperature.
Dirac constant: Planck constant, modified form; hbar Sometimes more suitable form of the Planck constant, stated as: hbar = h/(2 pi)

Hall Effect: Whenever charged particles flow via a tube that has both an electric field and a magnetic field (that is perpendicular to the electric field) present in it, only assured velocities of the charged particles are favored, and will make it un
