Question

A body falls freely towards the earth with

• A. uniform speed
• B. uniform velocity
• C. uniform acceleration
• D. none of these

Answer 1

The correct option is C

uniform acceleration

Explanation for correct answer

Option C

1. When a body falls freely towards the earth, it experiences a constant gravitational force equal to its weight.
2. Gravitational acceleration is the acceleration that an object receives as a result of the gravitational force $\left(g\right)$
3. In free fall, a body falls under the influence of gravity, which we believe is constant near the ground.
4. As a result, the body descends at a constant rate.
5. So, it falls with a uniform acceleration of $9.8m{s}^{-2}$.

Explanation for incorrect option

1. The speed or velocity of a free-falling body keeps on increasing till it touches the ground.
2. Because of the non-zero acceleration, the speed and velocity will change.
   Hence, options (A) and (B) are incorrect.

Hence, the correct answer is C.
