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.

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.
20 Ιουλ 2022 · A car, starting at rest at \(t = 0\), accelerates in a straight line for 100 m with an unknown constant acceleration. It reaches a speed of 20 \(m ⋅s ^−1\) and then continues at this speed for another 10 s.
A body moves with constant acceleration motion or uniformly accelerated rectilinear motion (u.a.r.m) when its trajectory is a straight line and its acceleration is constant and different from 0. This implies that the velocity increases or decreases its magnitude uniformly.
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.
