Question

Velocity-time graph of a particle freely falling under gravity would be straight-line parallel to the time axis.

• A. True
• B. False

Answer 1

The correct option is B False

1. When a particle falls freely under the effect of gravity, it accelerates towards the center of the earth with a uniform acceleration of $9.8m{s}^{-2}$.
2. Velocity-time graph of a particle freely falling under gravity would be straight-line but inclined at some angle with the time axis as shown below.
3. Velocity-time graph of a particle freely falling under gravity would be straight-line parallel to the time axis indicating that the particle's acceleration is zero which is not true.

Hence, the given statement is false.
