what is velocity time graph
Asked by akakhilesh15597 | 16 Sep, 2021, 08:37: PM
Expert Answer
When the object is in motion, its velocity, i.e, speed in specified direction is plotted as a function of time.
 
In x-axis time is considered and y-axis velocity is considered.
 
From the slope of velocity-time graph , we know the motion is uniform or accelerated motion.
 
Area under the graph between two time instances gives the distance travelled by the object in the the time duration .
 
In graph-(a) velocity is constant for all time . Hence it is uniform motion.
In graph-(b) velocity keeps on increasing , hence it is accelerated motion
In graph-(c) velocity keeps on decreasing, hence it is retarded motion.
 
Area between two time instances gives the distance travelled in the time duration.
