    Motion in a straight line is used to describe an object's movement along a straight line in a single direction. It is also known as the rectilinear motion. In Motion in a Straight Line, the position of the object changes along one dimension and unless an external force is applied, its direction stays constant. The important concepts related to straight-line motion are velocity, displacement and acceleration. Acceleration measures any change in velocity, displacement refers to the change in position and the velocity indicates the speed and direction. Examples include an apple falling straight downward, and a car moving on a straight roa

An example of the periodic motion is Earth's revolution. In this, the motion repeats itself after regular intervals of time. In oscillatory motion, the object moves back and forth about a mean position like a vibrating spring or pendulum. It is a type of periodic motion. Although, oscillatory motions are periodic, however, not vice versa. Oscillatory motion typically follows sinusoidal patterns and involves a restoring force.

When without slipping a body rotates and translates simultaneously is called rolling motion, such as a wheel on a road. It is the combination of rotatory and translatory motion. The point of contact has zero velocity relative to the surface in pure rolling. It is a condition in which there is no slipping or sliding during rolling.

According to the Class 11 Physics Chapter 6 System of Particles and Rotational Motion, for a rigid body to be in complete equilibrium, two conditions should be met:

  • Net external torque = 0 (rotational equilibrium)
  • Net external force = 0 (translational equilibrium)

The condition for equilibrium in rotational motion ensures that the body is not rotating or accelerating linearly. It is important in engineering and static structures to maintain stability like buildings or bridges.

To master the Class 11 Physics Chapter 3 Motion In A Plane, the students need to focus on thoroughly understanding vectors, and practice problems involving circular motion and projectile, for clarity, students should draw diagrams. They should memorize the key formulas, solve NCERT examples and attempt past year questions. For building strong conceptual clarity, they need regular practice with component resolution and vector addition.
