CBSE - Motion

1 Motion 

A ball is thrown vertically upwards. Which of the following plot represents the velocity time graph of the ball during its flight, if the air resistance is not ignored ?

2 Motion The acceleration of an object moving in a straight line can be determined from:
(1) The area between the distance-time graph and time axis.
(2) The area between the velocity-time graph and time axis
(3) The slope of the velocity-time graph.
(4) The slope of the distance-time graph.

3 Motion Which of the following graphs shows that the body is at rest?


(1) Graph-A
