Question

What can we conclude about the motion of a body depicted by following velocity-time speed time graph.

Answer 1

Answer:

1.body is moving with a constant velocity

2.body is moving with uniform velocity

3.body is decelerating

4.body is moving with constant speed

5.body is decelerating then it is at rest for some time and then continuing to move with a uniform velocity

Hope this helps...

Answer 2

Answer: The motions are : Uniform , uniformly accelerated , uniformly deaccelerated, body at rest, motion with change in direction.

Explanation:

1. In first graph, velocity is constant. Hence, the body will cover equal distance in equal intervals of time. The motion will be uniform.
   
2. In second graph, velocity increases linearly with time. The body starts from rest and moves with a constant acceleration. The motion is uniformly accelerated.
   
3. In third graph, velocity decreases linearly with time. The body starts from a initial velocity and moves with a constant deacceleration until the velocity becomes zero. The motion is uniformly deaccelerated.
   
4. In fourth graph, position remains constant with time. Hence, the velocity of the body is 0. The body remains at rest.
   
5. In fifth graph, first the position decreases linearly with time i.e., constant negative velocity. After reaching the position 0 , it remains at rest for some time. Then the position increases linearly with time i.e., constant positive velocity.
