Which of the graphs indicate negative acceleration? Why? (b) What do you infer from the graph where velocity time graph is parallel to the time axis? (c) Which of the graphs represent a body moving with initial velocity not equal to zero but with constant acceleration? Justify your answer. (d) Name the type of motion in which speed remains constant but the velocity of the body changes.
Answers
Answer:
(b) If velocity-time graph is parallel to x-axis it means velocity of object is constant(object is moving in a particular direction without changing it's direction & travelling equal distance in equal interval of the time).
(d) The direction changes at every point in a Uniform circular motion. Therefore, in uniform circular motion, the speed remains constant but the velocity keeps changing.
