Question

Describe the state of weightlessness with the help of a suitable example.

Answer 1

Explanation:

1. Weightlessness is a term used to describe the sensation of a complete or near-complete absence of weight.
2. In other words, weightlessness is a situation in which the effective weight of the body becomes zero.
3. For example, when a body is lying in a freely falling lift, then acceleration, a = g.
4. So, the effective acceleration due to gravity in the lift is,

$$\begin{gathered} g’=g–a \\ g’=g-g \\ g’=0 \end{gathered}$$

5. So, the weight of the body is equal to zero.

6. Another example is the astronauts in the spaceship will experience weightlessness almost, we witness them floating due to zero gravity.
