what is velocity time graph
Asked by akakhilesh15597 | 16 Sep, 2021, 08:37: PM
answered-by-expert 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.

Starting from rest, an object is uniformly accelerated to a speed of 60m/s in 20s. The object travels with this speed for next 40s and is then brought to rest by a uniform retardation in the next 30s.Sketch velocity time graph and calculate the acceleration, retardation and the total distance travelled. Hint: acceleration =rate of change of velocity.  distance covered =area under velocity-time graph .
