Define position, displacement, and distance traveled. Calculate the total displacement given the position as a function of time. Determine the total distance traveled. Calculate the average velocity given the displacement and elapsed time.
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: \(\begin{array}{l}Average\,Velocity = \frac{Total\,Displacement}{Total\,Time}\end{array} \)
Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt.
- 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!
Jul 20, 2022 · For any time interval, the quantity \(\left(v\left(t_{i}\right)+v\left(t_{f}\right)\right) / 2\), is the arithmetic mean of the initial velocity and the final velocity (but unfortunately is also sometimes referred to as the average velocity).
Formula for Average Velocity: Average velocity \((V_{avg})\) is calculated by dividing total displacement \((\Delta x)\) by the total time taken \((\Delta t)\). This is expressed as \(V_{avg} = \frac{\Delta x}{\Delta t}\).
Define position, displacement, and distance traveled. Calculate the total displacement given the position as a function of time. Determine the total distance traveled. Calculate the average velocity given the displacement and elapsed time.
Explain the relationships between instantaneous velocity, average velocity, instantaneous speed, average speed, displacement, and time. Calculate velocity and speed given initial position, initial time, final position, and final time.
