Q:

# What is the equation for velocity?

A:

The equation for velocity is displacement divided by time. The equations for speed and velocity are similar, but velocity must always have direction, whereas speed does not.

While speed is a measure of how fast something is moving, velocity is a measure of the rate an object changes its position. Distance is a measure of how far something is, while displacement is a measure of the shortest distance between an object's start point and its end point. For example, a runner who ran 400 meters around a track travelled a distance of 400 meters. However, he has a displacement of 0 because he ended up at the same place he started.

The most common equation for speed is: speed = distance / time. It can also be expressed as the time derivative of the distance traveled. Mathematically, it can be written as v = s/t, or v = (ds/dt), where speed is denoted by v, distance is denoted by s, and time is denoted by t. In case of uniform velocity, the first equation is used.

The equation to calculate a free-falling object's velocity or time spent falling is velocity equals gravitational acceleration multiplied by time. This occurs if three conditions are given: an initial velocity of zero, a hypothetical infinite space to fall in and negligible air resistance.
