Give examples for the following:
a) An object with constant acceleration but with 0 velocity
b) An object moving with an acceleration but with uniform speed
c) An object moving in a certain direction with an acceleration in the perpendicular direction
a) When an object is thrown up, at top most point velocity is zero but acceleration is still there which is due to gravity.
b) Object moving in circle under uniform circular motion. It moves with uniform speed although there is acceleration. Here acceleration is due to continuous change in direction.
c) When an object moves in circular motion then it has certain direction which is along tangent and an acceleration in the perpendicular direction to that.
