what is the mathematical formula for instantaneous velocity average velocity?
527775
The instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t: v(t)=ddtx(t). v ( t ) = d d t x ( t ) .

The dimensional equation of the average acceleration is [aa] = [LT. ... A body with a 1 m/s2 acceleration changes its velocity by 1 meter/second every second. Its magnitude (the "size" of the vector) is equal to the magnitude of the velocity variation vector divided by the elapsed time.

Using calculus, it's possible to calculate an object's velocity at any moment along its path. This is called instantaneous velocity and it is defined by the equation v = (ds)/(dt), or, in other words, the derivative of the object's average velocity equation.

Acceleration is a vector magnitude. The dimensional equation of the instantaneous acceleration is [a] = [L][T]-2 and therefore, its unit of measurement in the International System (S.I.) is the meter per second squared [m/s2].

Constant velocity is very different from average velocity. If an object traveled at 35 m/s for 20 s, it would travel the same distance in the same time as the previous example but in the second case, the object's velocity would always be 35 m/s.

The dimensional equation of the average acceleration is [aa] = [LT. The unit of measurement in the International System (S.I.) of the acceleration is meter per second squared (m/s2). A body with a 1 m/s2 acceleration changes its velocity by 1 meter/second every second.

Speed is a scalar, and average velocity is a vector. Average velocity indicates direction and can be represented as a negative number when the displacement is in the negative direction. Average speed does not indicate direction and can only be positive or zero.

Acceleration. Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

We have established that whenever v is constant on an interval, the exact distance traveled is the area under the velocity curve. ... If y=v(t) y = v ( t ) is a formula for the instantaneous velocity of a moving object, then v must be the derivative of the object's position function, s.

You can write this as a formula like this: a av = (Δv/Δt), where delta represents change. Next, use the information you know to work out the average acceleration. For example, if a car accelerated to 500 m/s over 10 seconds, divide 500 by 10 to get the average acceleration.

The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.

Velocity is the rate at which displacement changes with time. It is a vector, too. The average velocity over some interval is the total displacement during that interval, divided by the time. The instantaneous velocity at some moment in time is the velocity of the object right now!

['the formula is.', 's = ut + 0.5 at^2.', 'where s is the distance, u is the initial velocity (speed is the magnitude of velocity), a is the acceleration and t is the time.', 'Put all the values in the above formula and you will get an equation for t. ... ', 'You can also solve these two equations:']

constant speed is where the speed is the same throughout and instantaneous speed is speed given at any moment and average speed is a total distance traveled divided by the amount of time it took to travel it.

There are two ways to write this as a math formula: aav = Δv/Δt (The symbol Δ or "delta" just means "change.") aav = (vf - vi)/(tf - ti) In this equation, vf is the final velocity, and vi is the initial, or starting, velocity.

Another formula, acceleration (a) equals change in velocity (Δv) divided by change in time (Δt), calculates the rate of change in velocity over time. This formula may be written a = Δv ÷ Δt. ... In science, the units for acceleration usually will be meters per second per second (m/s/s) or meters per second squared (m/s2).

Calculate the value of the average velocity V of the flow by plugging in the values you determined for n, S and Rh into V = (k ÷ n) x Rh ^2/3 x S^1/2. For instance, if we found S = 3, Rh = . 125 ft, n = 0.024 and k = 1.486, then V will equal (1.486 ÷ 0.024s/(ft^1/3)) x (. 125 ft^2/3) x (3^1/2) = 26.81 ft/s.
