# How do you rearrange a level physics equations?

## What are the rules of rearranging equations?

• RULE #1: you can add, subtract, multiply and divide by anything, as long as you do the same thing to both sides of the equals sign.
• RULE #2: to move or cancel a quantity or variable on one side of the equation, perform the “opposite” operation with it on both sides of the equation.

## Why do we rearrange formulas?

When we rearrange an equation we change the form of the equation to display it in a different way. For example, the below three equations are rearranged forms of exactly the same equation. Typically we rearrange equations and formulas by using inverse operations to make one variable the subject of the formula.

## Who is the father of maths?

The Father of Math is the great Greek mathematician and philosopher Archimedes. Perhaps you have heard the name before–the Archimedes’ Principle is widely studied in Physics and is named after the great philosopher.

## What are the 4 equations of motion?

The equations are as follows: v=u+at,s=(u+v2)t,v2=u2+2as,s=ut+12at2,s=vt−12at2.

## What are the 3 kinematic equations?

The three equations are, v = u + at. v² = u² + 2as. s = ut + ½at²

## What does it mean to manipulate an equation?

Manipulating an equation means that you rearrange the equation so that the unknown you are trying to calculate is on its own on one side of the equation.

## How do you find velocity with VI and VF?

If you know the acceleration rate of the object, you can find the final velocity using the formula vf (final velocity) = vi (initial velocity) + a(t) (acceleration x time).
