Speed equal change of distance divided by change of time . Change of Speed (in meters/sec) Change of Time (in seconds)Acceleration (in meter/sec 2)∆V ∆T ∆V = V f - V i ∆T = T 2 - T 1 a = ∆S/∆T, not a = S/T. Why? If a car is traveling at ...
No. One cannot calculate the velocity of the object directly from the graph at a particular time. However, there is another way to find it. We can only find the change in velocity by the area under the acceleration time graph by calculating the area under the curve to the given time. T...

On the other hand, the acceleration of an object can be calculated from the velocity-time graph of the object, and its SI unit is m/s^2. What is the relationship between velocity and acceleration? The acceleration of an object is associated with the change in its velocity with time. ...
