Answer:
Types of Motions
The motion of an object shows its changing position, as discussed earlier. But varying objects show varying types of motion. Like for example, a fan is said to be in motion though it is static in its place or a hanging clock that shows motion though it is hanging in its position. We say that motion is mainly of three types: Rectilinear Motion, Circular Motion and Periodic Motion.
Explanation:
Circular Motion
Have you noticed the motion of a fan? Some objects are moving even though they are fixed at some position. Here the fan undergoes circular motion. In the circular motion, the objects follow a circular path of motion without changing their position. It is the circular movement of fan that results in cool air. Some more examples of circular motion are the motion of a Ferry wheel, satellites and rotation of planets around the sun.
Rectilinear Motion
In a rectilinear motion, all the objects move along a single line. Some common examples of rectilinear motion are marching soldiers, moving cars, and moving animals. The common thing in all these examples is that they move in a single line.
Periodic Motion
Have you ever seen a clock’s pendulum? It repeats its movement after a specific time. Physically the pendulum isn’t moving. It is fixed to some point, yet it shows motion. This kind of motion that repeats after a specific period of time is known as periodic motion. In the periodic motion, the movement made by these objects is called oscillation.
