Formula

Answer 1

Velocity: The changes happen in position is called velocity. Velocity is considered as the physical quantity. The magnitude and direction are necessary for this velocity.

Velocity Formula :Unit: metre/second

The formula for velocity is,

`v=d/t`

Here, the displacement is denoted as d and the time of the displacement is denoted as t.

Velocity = change in position over a specific time interval

v= (xf - xo)/(tf - to)

where xf is the final position and xo is the initial position.

where tf is the final time and to is the initial time.

Answer 2

A formula is a mathematical relationship or rule expressed using symbols and variables. It is used to calculate or describe the relationship between different quantities or variables in a given context. Formulas are fundamental in mathematics and are widely used in various fields such as physics, engineering, and finance.
