Question

a person standing on oscillating swing sits down.how does the the time period of swings get affected? what happens to the frequency of oscillation?​

Answer 1

Explanation:

The time period increases. It is because the centre of gravity of the system gets lowered in sitting position. This in turn increases effective length and hence the time period since

The frequency of oscillation decreases because

Answer 2

Answer:

Explanation:

Let us consider swing as a simple pendulum.

The time period of oscillation of simple pendulum is T = 2π√L/g

Length of the simple pendulum is equal to the distance from point of suspension to centre of gravity of the oscillating body.

(a). The time period increases. It is because the centre of gravity of the system gets lowered in sitting position.

(b). The frequency of oscillation decreases because frequency is inversely proportional to the time period i.e. f = 1/ T
