Which is the hardest science?

Physics. Generally, physics is often deemed to be the hardest of all the sciences, especially as an A level qualification. Physics involves a lot of complex maths content – an aspect that most students struggle with.

What is the SI unit of Ohm’s law?

Ohm’s law formula is written as; V ∝ I. Therefore, V = RI where R is a constant called resistance. R depends on the dimensions of the conductor and also on the material of the conductor. Its SI unit is Ohm (Ω).

What is the SI unit of resistance?

The SI unit of electric resistance is the ohm (Ω). 1 Ω = 1 V/A.

What is the most important formula in physics?

E=mc^2. For our first, we’ll take perhaps the most famous equation of all. Albert Einstein’s 1905 equation relating mass and energy is both elegant and superficially counterintuitive. It says that energy is equal to the mass of an object in its rest frame multiplied by the speed of light squared.

What is the hardest physics formula?

Yet only one set of equations is considered so mathematically challenging that it’s been chosen as one of seven “Millennium Prize Problems” endowed by the Clay Mathematics Institute with a $1 million reward: the Navier-Stokes equations, which describe how fluids flow.

What is the basics of physics?

Physics is a study of how the universe behaves. Physics is a natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the study of nature in an attempt to understand how the universe behaves.
