Physics
A cyclist taking a turn on a road is an example of …………… motion.
- rectilinear
- translatory
- curvilinear
- circular
Answer
curvilinear
Reason — When a cyclist takes a turn, the path followed is curved, so the motion is called curvilinear motion.
- It is not rectilinear motion because rectilinear motion occurs along a straight line, whereas the cyclist is moving along a curved path.
- It is not translatory motion as the best description here, although the cyclist does move from one place to another; this term does not specify the nature of the path (straight or curved), so it is not the most appropriate answer.
- It is not circular motion because circular motion requires movement along a fixed circular path with a constant radius and a definite centre, which is not the case when a cyclist takes a turn.
Hence, the cyclist taking a turn on a road is an example of curvilinear motion.
