Ncert Exercises & Solutions

The motion of a ball bearing inside a smooth curved bowl, when released from a point slightly above the lower point is

(a) simple harmonic motion

(b) non-periodic motion

(d) periodic but not SHM

Choose the correct alternatives:

1. (a, b)

2. (a, d)

3. (c, d)

4. (b, c)

(1) Hint: In a periodic motion, the body repeats its motion after a certain time interval.

The motion of the ball bearing will be an SHM but non-periodic as the ball bearing loses its energy due to friction.
