Question

What can we conclude about the motion of a body depicted by the following velocity-time graphs:

Answer 1

1. It represents the body moving with a uniform velocity. That is the velocity of the body doesn't change with time.
2. It represents the body's velocity increases uniformly i.e the body is having uniformly accelerated motion.
3. It represents that the velocity of the body decreases uniformly with time and finally becomes zero. Thus, this graph represents uniformly retarded motion.
4. It represents the body first retarding uniformly then coming to rest and staying at rest for some time and then accelerating uniformly.
