Types of Motion

When an object moves in a straight line or in the same direction, it is called linear motion. For example, a train moving on a track or a car driving on a straight road. 

Types of Linear Motion:

1. Uniform linear motion: When an object covers the same distance in equal intervals of time, its motion is called uniform linear motion. For example, soldiers marching in a parade at the same speed.
2. Non-uniform Linear Motion: When an object covers different distances in equal intervals of time, its motion is called non-uniform linear motion.For example, a girl sliding down a slide, where she starts slow but moves faster as she reaches the bottom.

Examples of linear motion 

When an object moves in a path that is not a straight line, it is called non-linear motion.

Types of Non-linear Motion:

1. Oscillatory Motion: When an object swings back and forth, it is called oscillatory motion. Examples include a swing moving back and forth, the pendulum of a clock, or the vibrating strings of a guitar.
2. Circular Motion: When an object moves in a circular path, it is called circular motion. For example, the hands of a clock, a fan, or a merry-go-round that moves in a circle.
3. Periodic Motion: When an object repeats its motion at a regular interval of time, it is called periodic motion. For example, the minute hand of a clock completes one round every 60 minutes, and a merry-go-round rotates at the same time for each round.
4. Random Motion: When an object moves in no definite direction and its speed changes constantly, it is called random motion. Examples include a butterfly flying from one flower to another or football players moving around the field during a game.
