FAQs on Rolling and Sliding - Explanation (English) Video Lecture - Mathematics for Class 1: NCERT

1. What is the difference between rolling and sliding?
Ans. Rolling is a type of motion where an object moves by rotating on its axis, while sliding refers to the motion of an object moving without any rotation. Rolling requires a circular or cylindrical shape, while sliding can occur with any shape.
2. Can an object both roll and slide at the same time?
Ans. No, an object cannot both roll and slide at the same time. Rolling and sliding are two distinct types of motion. An object can either roll or slide depending on its shape and the surface it is moving on.
3. What are some examples of objects that roll?
Ans. Some examples of objects that roll include a ball, a wheel, a rolling pin, a log, and a cylinder. These objects have a circular or cylindrical shape that allows them to roll smoothly.
4. How does friction affect rolling and sliding?
Ans. Friction plays a significant role in both rolling and sliding motions. In rolling, friction helps provide traction and enables the object to roll smoothly. In sliding, friction acts opposite to the motion, opposing the object's movement and causing it to slow down or stop.
5. Which is more efficient, rolling or sliding?
Ans. Rolling is generally more efficient than sliding. When an object rolls, it experiences less friction compared to sliding, as the contact points between the object and the surface are constantly changing. This reduces the amount of energy required to keep the object in motion. Sliding, on the other hand, requires more energy to overcome the friction acting against the motion.
