Distance and displacement both refer to how far an object has moved, but the meanings are different. The distance is a scalar quantity and it is the total length covered by an object, irrespective of the direction. It is always positive, and talks about how much ground the object has covered. On the other hand, displacement is the vector quantity and refers to the change in position of an object from the initial to the final point. It considers both the magnitude and direction. It can be negative, positive or zero depending on the motion's direction. If one starts from an initial point and covers a distance of 5 meters and then comes b

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.
