Equation \ref{eq5} reflects the fact that, when acceleration is constant, \(v\) is just the simple average of the initial and final velocities. For example, if you steadily increase your velocity (that is, with constant acceleration) from 30 to 60 km/h, then your average velocity during this steady increase is 45 km/h.

The equation v – = v 0 + v 2 reflects the fact that when acceleration is constant, v – is just the simple average of the initial and final velocities. Figure 3.18 illustrates this concept graphically. In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate.
21 Νοε 2023 · It is calculated by a = (V-Vo)/t, where a is acceleration, V and Vo are final and initial velocities, and t is time. What is Constant Acceleration? Acceleration is the rate of change in...
The equation \(\bar{v} = \frac{v_{0} + v}{2}\) reflects the fact that when acceleration is constant, v is just the simple average of the initial and final velocities. Figure \(\PageIndex{1}\) illustrates this concept graphically. In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate.
If there is no acceleration, we have the formula: s =vt where s is the displacement, v the (constant) velocity and t the time over which the motion occurred. This is just a special case (a = 0) of the more general equations for constant acceleration below.
Velocity is directly proportional to time when acceleration is constant (v ∝ t). Displacement is proportional to time squared when acceleration is constant ( ∆ s ∝ t 2 ). Combining these two statements gives rise to a third — one that is independent of time.
Constant acceleration equations. These equations relate displacement, velocity, acceleration, and time, and apply for constant acceleration in the +x direction starting at t=0. v = v o + at (1) x = x o + v o t + ½ a t 2 (2) Using Eq. (1), at = v - v o, in Eq. (2), we get: x = x o + v o t + ½ (v - v o) t
