Velocity Time Graph

This is physics class of class 9th in which I have discussed the velocity-time graph in detail having proper explanation with the help of examples .This is actually the topic of the chapter Motion here.You don't need to keep anything while attending the class ,only your concentration towards the class is sufficient.I hope this lecture will b helpful for you.First and have discussed a brief explanation of graph then I have started my class with the 3 general cases that we usually study in the velocity time graph.First case is when the body is in uniform motion ,the graph is horizontal parallel to time axis.The second case is when the body is in uniform acceleration,the graph and n that s case is straight line inclined at an angle with the time axis.The last case is when the body is in non uniform acceleration.the graph is curved line here,there are other special cases which we will study in next lectures.I hope u will enjoy the sessions here
