Types of Motion

Boojho was riding on his bicycle along a straight road. He classified the motion of various parts of the bicycle as (i) rectilinear motion, (ii) circular motion and (iii) both rectilinear as well as circular motion. Can you list one part of the bicycle for each type of motion? Support your answer with reason.

How are the motions of a wheel of a moving bicycle and a mark on the blade of a moving electric fan different? Explain.

While travelling in a train, it appears that the trees near the track are moving whereas co-passengers appear to be stationary. Explain the reason.

Paheli moves on a straight road from point $\mathrm{A}$ to point $\mathrm{C}$. She takes $20 \mathrm{minutes}$ to cover a certain distance $\mathrm{AB}$ and $30 \mathrm{minutes}$ to cover the rest of distance $\mathrm{BC}$. She then turns back and takes $30 \mathrm{minutes}$ to cover the distance $\mathrm{CB}$ and $20 \mathrm{minutes}$ to cover the rest of the distance to her starting point. She makes $5$ rounds on the road the same way. Paheli concludes that her motion is
