## What is current formula?

Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.

## How do u calculate force?

Force exerted by an object equals mass times acceleration of that object: F = m * a .

## 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 most powerful equation?

Einstein’s E=mc² is the world’s most famous equation. Simple as that. It is short, it is elegant, and it describes a phenomenon so crucial that everyone should know about it.

## Why is E mc2 so famous?

But its fame is mostly because of its association with one of the most devastating weapons produced by humans – the atomic bomb. The equation appeared in the report, prepared for the US government by physicist Henry DeWolf Smyth in 1945, on the Allied efforts to make an atomic bomb during the Manhattan project.

## Is physics easy or hard?

Students and researchers alike have long understood that physics is challenging. But only now have scientists managed to prove it. It turns out that one of the most common goals in physics—finding an equation that describes how a system changes over time—is defined as “hard” by computer theory.

## What is the formula for final velocity?

Final velocity (v) squared equals initial velocity (u) squared plus two times acceleration (a) times displacement (s). Solving for v, final velocity (v) equals the square root of initial velocity (u) squared plus two times acceleration (a) times displacement (s).

## What is 1st equation of motion?

The first equation of motion is v = u +at. Here, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time.

## What is the formula of energy?

Energy is defined as the capacity to do work. Formula. The energy stored in an object due to its position and height is known as potential energy and is given by the formula: P.E. = mgh. Unit.

## What are the formula of 3 laws of motion?

The formula of 3 laws of motion are ……. 1) Every object stays in the same position until an external force is applied on it. 2) F = ma. 3) An action has an equal and opposite reaction.

## What is a in f ma?

For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration) are both vector quantities.

## What is current SI unit?

ampere. The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 x 10-19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ΔνCs. Unit of.

## Why is Ohm’s law important?

Why Is Ohm’s Law Important? Ohm’s law is vitally important to describing electric circuits because it relates the voltage to the current, with the resistance value moderating the relationship between the two.

## What is a formula of resistance?

V is the potential difference in volts , V. I is the current in amperes (amps), A. R is the resistance in ohms, Ω The equation can be rearranged to find the resistance: R = V ÷ I Question.

## What is the mass formula?

One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.

## How do I calculate friction?

The coefficient of friction (fr) is a number that is the ratio of the resistive force of friction (Fr) divided by the normal or perpendicular force (N) pushing the objects together. It is represented by the equation: fr = Fr/N.

## What is equal velocity?

The velocity is the time rate of change of displacement. If ‘S’ is the displacement of an object in some time ‘T’, then the velocity is equal to, v = S/T.
