1.	A ball is thrown vertically , draw it\'s a) velocity - time curve, b) acceleration - time curve
Answer» When the ball is thrown vertically upward its velocity decreases as it moves upward due to the gravitational force acting on it downwards and thus the graph slopes downwards with a negative gradient.When it reaches a certain height, that is at a stationary point, the velocity becomes zero and at this point the graph cuts the x axis.The ball then comes back with an increasing velocity from zero to its initial position and at this point the graph slopes downwards from the x axis.
