Question

Draw a velocity-time graph for the free-fall of a body under gravity starting from rest.
(Take g = 10 ms–2)

Answer 1

Velocity-time graph for the free-fall of a body under gravity

Explanation:

For a free-falling object that starts from rest, the object is under acceleration due to gravity (10 m/s2). When we plot a graph between velocity and time, you would observe that the graph is linear and consists of a diagonal line. This signifies an accelerated motion. The initial velocity is zero. And the object finishes with a large, negative velocity. The object is moving in the negative direction and speeding up. So the object has negative acceleration.
