what do you mean by average velocity describe in 500 words
Answers
Explanation:
Velocity can be defined as “speed having direction”. As you can understand from the definition velocity is a vector quantity having both magnitude and direction. In daily life we use speed and velocity interchangeably but in physics they have different meanings. We can define velocity as the “rate of change of displacement” whereas “the speed is rate of change of distance”. While we calculate speed we look at the total distance, however, in calculating velocity we must consider the direction and in short we can just look at the change in position not the whole distance traveled. If a man walks 5m to east and then 5m to west speed of that man calculated by dividing total distance traveled which is 10m to the time elapsed, however, velocity calculated by dividing the displacement to the elapsed time, which is 0m divided elapsed time gives us zero. In other words, if the displacement is zero we can not talk about the velocity.

The average velocity of an object is its total displacement divided by the total time taken. In simple words, it is the rate at which an object changes its position from one place to another. Average velocity is a Vector quantity. The SI unit is meters per second. However, any distance unit per any time unit can be used when necessary, such as miles per hour (mph) or kilometer per hour (kmph).
