Motion of an electric fan is _____ ? 

The correct answer is Circular motion.

Key Points

• Circular motion:
  • The motion of an electric fan is an example of circular motion because the blades of the fan move in a circular path around a fixed axis.
  • In circular motion, objects move in a circle or a circular path with a constant distance from the center.
  • Key characteristics include constant speed but changing velocity due to continuous change in direction.

Additional Information

• Rectilinear motion:
  • Rectilinear motion refers to motion along a straight line.
  • Examples include a car moving on a straight road or an object falling freely under gravity.
  • Since the blades of an electric fan do not move in a straight line, this option is incorrect.
• Periodic motion:
  • Periodic motion is motion that repeats itself at regular intervals of time.
  • Examples include the swinging of a pendulum or the oscillation of a spring.
  • While the motion of a fan can be periodic, it is more accurately described as circular motion due to the path of the blades.
