Average Velocity is defined as the total displacement travelled by the body in time t. The average velocity is denoted by V av and can be determined using the following formula: \ (\begin {array} {l}Average\,Velocity = \frac {Total\,Displacement} {Total\,Time}\end {array} \) Based on the values given, the above formula can also be written as:

The formula of average velocity is as follows: average velocity = (endposition)–(startposition) (endtime)–(starttime) vavg = x2–x1 t2–t1. Derivation of the Formula. vavg = refers to the average velocity in meter per second. x1 = refers to the starting position of the object in meter/s. x2 = refers to the ending position of the object in meter/s.

- There is not that much of a difference, but there are a few very important but subtle ones. 1) Speed is a scalar (only magnitude) and Velocity is a...
- Seems highly probable.
- Thats a nice question.... In a way, you are asking the question "what is the point in vectors...?" vectors contain more information than scalars an...
- You would have to use the distance traveled. For example, if you were stopped by a police officer, going 70 mph (average) in a 55 mph zone, he/she...
- Magnitude is the relative size or extent but measurement is the numerical amount.
- If you were referring to speed, you would be right, but since we are dealing with velocity, a *vector,* which in a previous video he explained that...
- Constant velocity here means that his velocity was not changing so neither his speed nor his direction would change, everything would remain constant.
- Hi Viveka, You don't know this yet but you have just asked a very important question. A question that will change the way you view the world and ho...
- According to convention, we use "s" for displacement, after the latin word "spacium"—same idea though!
Mar 31, 2023 · Use this formula to find average velocity. If and only if the acceleration is constant, the average velocity is the same as the average of the final velocity and the initial velocity: (v f + v i )/2 .
