Question

Identify the uniform motion among the following:

• A. Rotation of Earth
• B. A train entering into a railway station
• C. Movement of a housefly
• D. Movement of the hands of a wall clock

Answer 1

Answer: (A), (D)

Movement of the hands of a wall clock

• An object is said to be in uniform motion when it covers equal distances in equal intervals of time.
• Earth and the hands of a clock move at their constant speeds. So these two are examples of uniform motion.
• The movement of a housefly and a train entering a railway station is an example of non-uniform motion as it changes its speed randomly.
