Question

A mass is dropped from a height h above the ground, and freely falls under the influence of gravity. Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling? Consider the "up" direction to be positive.

Which graph is it?​

Answer 1

Answer:

B

Explanation:

The only force acting on the block is gravity, so the block has a constant, negative acceleration. This means the velocity of the block is decreasing at a constant rate, so the answer is B, D, or E. Velocity is the rate of change of displacement, and answer choice B is the only one that has a displacement graph that matches that idea.

Answer 2

Answer: Graph B here correctly describes the displacement and velocity of the object during the time the object is falling. Option B is correct.

It is given that the mass of an object is dropped from height 'h' above the ground and "up" direction is taken to be positive.

It is required to find the graph which describes the displacement and velocity of the object during the time the object is falling.

Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling?

If any body falls freely towards the ground, then its acceleration is decreasing constantly with respect to time. That means velocity of an object will also be decreased as shown in graph B. Also we know that velocity is the rate of change of displacement.

As it is given in question that up direction is positive then it is also considered that downward be negative means decreasing.

Therefore, both the quantities are decreasing. So graph B correctly describes the displacement and velocity of the object during the time the object is falling.
