# Speed Velocity and Acceleration problems

## The main difference between speed and velocity involves

Speed is defined as:
The distance covered by an object in a unit of time is said to be its speed.

speed formula:

However, Velocity is defined as:
The rate of change of displacement of anybody is said to be velocity.

## which explains the information needed to calculate speed and velocity?

For calculation of speed, we require distance covered and taken time

it is denoted by v and its formula is:

v\;=\;\frac st

S is Distance and t is time.

However, For the calculation of velocity, we require displacement of that moving body and take time.

it is also denoted by v and its formula is:
v\;=\;\frac dt

### when is the average velocity of an object equal to the instantaneous velocity?

If the acceleration of an object is zero then the average Velocity is equal to instantaneous velocity. And if the acceleration of an object is zero there can be no change in speed or direction of that object.

### which pair of sentences is describing the same velocity?

A moving car and a truck have the same velocity.

Actually, acceleration is a rate of change of velocity and velocity is a rate of change of position. So the position, velocity, and acceleration are related to each other.
