Q.No.3.7: - Motion with constant velocity is a special case of motion with constant acceleration. Is this statement true? Discuss.
Ans: - Yes this statement is true because when the body moves with constant velocity then its acceleration will be zero and zero is itself a constant value so we can say that acceleration is also constant during constant velocity.
This answer is wrong. Because when velocity is constant. There is no acceleration. Graphically a line is obtained parallel to time axis. Horizontal line.
ReplyDeleteEither a body is accelerating or non acvelerating. a=0, does not mean that accekeration is constant.(if speed v=0, then what would u say.thay speed is constant? Here u said that speed is zero.
ReplyDeleteThis statement is not true, rate of change of velocity is called acceleration, so when there is no change in velocity, there will be no acceleration
ReplyDeleteIts answer should be.....
ReplyDeleteYes, the statement is true, if an object is moving in a circle with constant velocity, the magnitude of acceleration produced due to change in direction at every point will also be constant.
Yes ' the statement is true.
