Is Velocity Equal to a*t in an Acceleration vs Time Graph?

Click For Summary
In an acceleration vs. time graph, velocity at t=0 does not have to be zero; it depends on the initial conditions. The equation v = v0 + at indicates that velocity can be calculated using initial velocity (v0), acceleration (a), and time (t). If the initial velocity (v0) is not zero, then the velocity at t=0 will also not be zero, regardless of acceleration. The confusion arises from assuming that acceleration alone determines velocity without considering initial velocity. Understanding these relationships is crucial for accurately interpreting motion in physics.

is the velocity at t=0 in acceleration vs time graph must be 0 .please answer my question

Not necessarily.

but why the velocity = a*t so v=4*0=o m/s

$$v=v_0+at$$
