For any equation of motion s(t), we define what we call the instantaneous velocity at time t-- v(t) -- to be the limit of the average velocity, , between t and t + Δt, as Δt approaches 0. When we compute average velocity, we look at To obtain the (instantaneous) velocity, we want the change in time to “go to” zero. 1. Although average velocity is useful in describing the motion of an object over a certain time interval, it can’t describe the motion of an object at an instant in time during the interval. 3 Piston Instantaneous Acceleration. A speedometer in the car gives an instantaneous speed as it gives the speed of the moving car at that specific time, whereas the average speed would be used as a measure of The displacement (in meters) of a particle moving in a straight line is given by s=t^2-8t+17, where t is measured in seconds. Instantaneous voltage = Maximum voltage x sin θ. The calculus representation is the derivative of v with respect to t, or dv/dt. Therefore when calculating instantaneous speed using the limiting process described above for velocity, we get that instantaneous speed at time t is equal to the absolute value of the instantaneous velocity: speed at time t = lim t!0 js(t+ t) s(t)j t = js0(t)j= jv(t)j; direction, while speed is a scalar. ’ Final Velocity: Brake Horsepower.
