Types of Motion- Science Animation Let us first understand what is motion? When the boy starts cycling, the boy is said to be in motion. When any object is in motion it is always relative to another object. Here the boy who is cycling is moving with respect to tree which is stationary that is not moving. We can also say that the tree is at rest. The position of boy changes with time. Thus we say that the state of the change in place or position of a body with respect to time and relative to an object (tree) is said to be motion. If a body does not change its position with respect to time, then it is said to be at rest. (tree) There are different types of motion which we will learn through an example. • Translatory motion • Circular motion • Oscillatory motion (1) Translatory motion A motion in which all parts of the moving body move toward the same direction is said to be translator motion. Example: A car or a boy cycling in a straight line or curved line is an example of translator motion. All the parts of the object move through the same distance. There are two types of translator motion: (a) Rectilinear motion (b) Curvilinear motion Rectilinear motion is the motion of a body in a straight line. Examples of bodies in rectilinear motion is car moving along a straight track . Curvilinear motion Curvilinear motion is the motion of a body on a curved path. Examples of bodies in curvilinear motion is car moving along a curved track . (2) Circular motion When a body moves along a circular path, it is said to be in circular motion. Examples of bodies in circular motion are the rotating blades of a fan. There are two types of circular motion: (a) Rotatory motion (b) Revolutionary motion (1) Rotatory motion When an object moves around an axis in such a way that they do not change their position from one place to another is called rotator motion. Example: The arms of a watch rotates in circular motion but do not change their position on the whole. (2) Revolutionary motion The objects moving on a circular path which change their position on the whole from one place to another are said to be in revolutionary motion. Example: Planets moving around the sun. (3) Oscillatory motion When a body or object moves to and fro it is called oscillation but when this is around a main point or position it is said to be oscillatory motion. The best example of oscillatory motion is the pendulum of a clock.
