• C. Motion of spinning top
• D. Moving hands of clock

Answer 1

The correct option is B

Motion of a discus

Explanation for correct answer:

2. Some examples of curvilinear motion are the motion of a train along a curved track and the motion of a discus in discus throw.

Explanation of incorrect answer:

A) Ball falling vertically

1. When a ball is falling vertically then it will be rectilinear motion.

C) Motion of spinning top
