Question

circle the odd one out movement of clock hands , fan , merry - go - round , parade of soldiers

Answer 1

parade of soldiers is odd because the other are eg of circular motion

Answer 2

'A parade of soldiers' is the odd one out as it is a form of linear motion, while the others are circular motion.

• The movement of the hands of a clock, a fan and a merry-go-round are examples of circular motion as they move around a fixed point. Circular motion can be uniform, with constant angular rate of rotation and speed. It can also be non-uniform with varying rate of rotation.
• In linear motion, the object moves along a straight line, in one dimension. This can be of two types- rectilinear where the object moves along a straight line, and curvilinear where the object moves along a curved path.
• Linear motion theoretically follows Newton's first law of motion which states that an object continues to move along a straight path unless an external force is applied.
