What Are the Types of Motion?

Motion is broadly classified into two types: uniform and non-uniform. The latter is further divided into three categories: translatory, vibratory and rotatory. Based on the path of the movement, translatory motion can either be rectilinear or curvilinear.

Motion is one of the governing principles in physics. It pertains to the variation between the initial and final location of an object. Motion can also refer to the action of moving or being moved. A body is said to be at rest when it remains fixed in its position in relation to its environment. An object, meanwhile, is said to be in motion if its position is altered in relation to its surroundings.

Uniform motion occurs when the distance traveled by an object is equal to the amount of time it takes to cover that particular distance. For instance, a vehicle running at a steady rate has uniform motion. Non-uniform motion occurs when an object is not moving at constant speed or velocity. Translatory motion depends on what path the object the body is traveling along. Rectilinear motion is movement along a straight line while curvilinear motion is movement along a curved path or surface. A man walking on even ground is an example of rectilinear motion while a car rounding a curve demonstrates curvilinear motion. Rotatory motion refers to moving around in a circular path, such as the spinning wheels of a car. Vibratory motion is an oscillating movement where an object swings in a back and forth manner. An example of this is the pendulum of a grandfather clock.
