Consider the following statements about friction. 1. Heat is generate...
Heat generation due to friction:
- Statement 1 is correct as heat is indeed generated when two surfaces rub against each other, converting mechanical energy into thermal energy.
Increased friction in Kabaddi:
- Statement 2 is correct as Kabaddi players rub dust on their hands to increase friction, which helps them get a better grip on their opponents.
Fluid friction known as drag:
- Statement 3 is correct as the friction applied by fluids, such as air or water, is referred to as drag. This drag force opposes the motion of an object through the fluid.
Sliding friction vs. static friction:
- Statement 4 is correct as sliding friction is generally less than static friction. Static friction is the force that keeps an object at rest, while sliding friction is the force resisting the motion of an object already in motion.
Therefore, all the given statements (1, 2, 3, and 4) about friction are correct.
- Statement 1 is correct as heat is indeed generated when two surfaces rub against each other, converting mechanical energy into thermal energy.

- Interlocking between two surfaces in contact is the reason behind friction. In the absence of friction, we will be unable to hold a pen or pencil. It is due to friction that a matchstick catches fire on rubbing.
- Friction causes heat. Kabaddi players rub sand/dust on their hands, which increases friction. Substances which decrease friction are called lubricants. Water and other fluids also apply friction on the objects that move across them.
- Friction applied by fluids is called ‘drag’. When an object slides over a surface, it applies sliding friction on it. Sliding friction is less than static friction.
