Give Reasons:

1. The acceleration of a moving Bec. final speed is greater than
object ispositive. initial speed.

2. The body moves by Bec. the body which moves with
acceleration can'tmove with acceleration its speed changes
constant velocity. by time.

3. Distance-time graph for an Bec. object covers equal
distance inequal interval time
object
moves at uniform speed is a
straight linepassing through the
origin point.

4. Speed-time graph for an Bec. speed of object is constant
as timepasses.
object moves
at regular speed is a straight line
parallelto the time axis.

5. When the driver of a Bec. speed of car will decrease

moving car uses the brakes, we withtime.
describe the car’s
movement as decelerating motion.
