 1. What is rotational motion?
Ans. Rotational motion refers to the movement of an object around its axis or center of rotation. In this type of motion, every particle of the object moves in a circular path, maintaining a fixed distance from the axis. Examples of rotational motion include the spinning of a wheel, the rotation of Earth on its axis, or the swinging of a pendulum.
 2. How is rotational motion different from linear motion?
Ans. Rotational motion and linear motion differ in terms of the path followed by the object. In linear motion, an object moves along a straight line, while in rotational motion, an object moves along a circular path. Additionally, linear motion involves translational displacement, whereas rotational motion involves angular displacement measured in terms of angles.
 3. What is a heavy pulley in rotational motion?
Ans. A heavy pulley in rotational motion refers to a pulley system that has a significant mass and experiences rotational motion when a force is applied to it. The heavy pulley is usually connected to other objects or systems, and when a torque is applied to the pulley, it rotates, causing the connected objects to move accordingly.
 4. How is torque related to rotational motion?
Ans. Torque is a measure of the tendency of a force to rotate an object about an axis. In rotational motion, torque plays a crucial role as it causes objects to rotate. The magnitude of torque depends on the applied force, the distance from the axis of rotation, and the angle between the force and the lever arm. Mathematically, torque is given by the formula: Torque = Force × Lever Arm.
 5. What are the applications of rotational motion in everyday life?
Ans. Rotational motion finds numerous applications in our everyday lives. Some examples include the rotation of wheels in vehicles, the spinning of a fan or a blender, the swinging of a pendulum in a clock, the rotation of Earth on its axis causing day and night, and the spinning of a record player. Understanding rotational motion helps in designing and analyzing various mechanical systems and devices.
