From the given v-t graph it can be inferred that an object is

State whether true or false. If false, correct the statement.
Acceleration can get negative value also.
Assertion: A negative acceleration of a body can be associated with speeding up of the body.
Reason: Increase in the speed of a moving body is independent of its direction of motion.
