Question

a ball is thrown vertically upwards. Draw it's (I) velocity time curve (ii) acceleration time curve​

Answer 1

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.

The image shows the graph.
