Question

Which of the following is/are good example(s) of non-uniform motion?

• A. When an object is moving in a circular path with uniform speed
• B. A car is travelling in an overcrowded zigzag road
• C. Motion of a pendulum
• D. Both B and C

Answer 1

Answer: (D)

An object covering equal distances in equal time interval, i.e. moving with a uniform speed is said to be in a uniform motion.

An object moving in a circular path with uniform speed is said to be in a uniform circular motion.

Since, in a motion of a pendulum and in a car travelling in an overcrowded zig zag road, the speed of the object is changing and is not uniform, hence they are examples of non-uniform motion.

SO, both options B and C are correct.
