## Types of Motion – Class 11 | Chapter – 3 | Physics Short Notes Series PDF for NEET & JEE

Types of Motion: Motion refers to the change in position of an object with respect to time. In physics, motion can be described in terms of displacement, velocity, acceleration, and time. Motion can also be classified based on the type of path followed by the object. For example, rectilinear motion refers to motion along a straight line, while circular motion refers to motion along a circular path. Understanding the different types of motion is important for understanding how objects move and interact with each other in the natural world.

## Types of Motion

There are different types of motion that describe how objects move. Some of the most common types of motion include:

• Rectilinear motion: This type of motion involves an object moving along a straight line. The object’s speed and direction can change, but it always moves along the same path.
• Circular motion: In circular motion, an object moves around a fixed point or axis. The object’s speed and direction are constantly changing, but its path is circular.
• Periodic motion: Periodic motion is any motion that repeats itself over and over again. Examples include the motion of a pendulum, the rotation of a planet around its axis, and the oscillation of a spring.
• Projectile motion: Projectile motion is the motion of an object that is thrown or launched into the air and then moves along a curved path under the influence of gravity. Examples include a basketball being thrown into a hoop or a rocket being launched into space.
• Oscillatory motion: Oscillatory motion is any motion that involves a back-and-forth movement around a fixed point. Examples include the motion of a pendulum, a swing, or a vibrating guitar string.
• Rotational motion: Rotational motion is the motion of an object that spins or rotates around a fixed axis. Examples include the rotation of a wheel or the spinning of a top.
• Translational motion: Translational motion is the motion of an object that moves without rotating or spinning. Examples include the motion of a car driving along a straight road or a ball rolling down a hill.
