is the velocity at t=0 in acceleration vs time graph must be 0 .please answer my question
but why the velocity = a*t so v=4*0=o m/sChestermiller said:
$$v=v_0+at$$ahmed emad said:
An acceleration vs time graph is a visual representation of an object's acceleration over a period of time. It shows how an object's velocity changes over time, with acceleration on the y-axis and time on the x-axis.
To read an acceleration vs time graph, you must first determine the units of acceleration and time being used. Then, you can look at the slope of the graph at any given point to determine the object's acceleration at that time. A steeper slope indicates a higher acceleration, while a flatter slope indicates a lower acceleration.
A horizontal line on an acceleration vs time graph represents a constant acceleration of 0 m/s². This means that the object is moving at a constant velocity and is not accelerating or decelerating.
The slope of an acceleration vs time graph represents an object's velocity. A positive slope indicates a positive velocity, while a negative slope indicates a negative velocity. The steeper the slope, the faster the object is accelerating.
A curved line on an acceleration vs time graph represents an object's changing acceleration. The shape of the curve can indicate whether the object is accelerating at a constant rate, accelerating at an increasing rate, or decelerating. The steeper the curve, the greater the change in acceleration over time.
