Definition: Average Velocity is displacement over total time. Mathematically: ... Graphical interpretation of velocity: Consider 1-d motion from point P (with coordinates xi , ti ) to point Q (at xf , tf ). We can plot the trajectory on ... ; Next: Instantaneous Velocity Up: Motion in One Dimension Previous: Displacement;

Section 2. Average Velocity and Instantaneous Velocity ... The instantaneous velocity shows the velocity of an object at one point. For example, when you are driving a car and its speedometer swings to 90 km/h, then the instantaneous velocity of the car is 90 km/h.

Now the idea of average velocity is something that is fairly straightforward, but the idea of instantaneous velocity is a little trickier. It really requires calculus to fully appreciate, but hopefully you already know what a derivative is, so this shouldn't be too hard.

The meaning of instantaneous velocity. Related rates. ... For any kind of motion, then, uniform or not, we define the instantaneous velocity at the time t to be the limit of the average velocity, Δs/Δt, as Δt approaches 0.

We can define the instantanous velocity as a limit of an average velocity, as the time interval gets smaller and smaller. Let s (t) be the position of an object at time t. The instantaneous velocity at t = a is defined as .

Instantaneous velocity is average velocity extrapolated to zero time interval. ... The instantaneous speed is always the magnitude of the instantaneous velocity. ... Unless explicitly stated otherwise, the words speed and velocity are assumed to be instantaneous quantities.

Physics 1051 - Instantaneous velocity page ... At a first guess, we might try to get an approximate value for the velocity v at t=2 seconds by evaluating the average ... The result is an average velocity of -2.15 m/s. Is this a good approximation to the true velocity of the object over the 3-second interval? Not really.

Physics 1051 - Instantaneous velocity page ... We can define the average velocity of a object moving in one dimension as follows: ... How can we define velocity if the motion of an object is NOT uniform? For instance, in the plot below, how can we define the velocity at a time t = 2 seconds?
