FAQs on Friction - Additional Study Material for NEET

1. What is friction?
Ans. Friction is a force that opposes the motion of an object when it comes into contact with another object or surface. It is caused by the roughness of the surfaces in contact and can either slow down or stop the motion of an object.
2. How does friction affect the motion of an object?
Ans. Friction can have different effects on the motion of an object. It can cause the object to slow down or stop, as it opposes the direction of the motion. Friction can also create heat due to the resistance between surfaces, which can further impact the motion of the object.
3. What factors affect the amount of friction between two surfaces?
Ans. The amount of friction between two surfaces is influenced by several factors. These include the roughness of the surfaces, the force pressing the surfaces together, and the type of material the surfaces are made of. Smoother surfaces, higher force, and rougher materials generally result in higher friction.
4. Can friction be both beneficial and detrimental?
Ans. Yes, friction can have both positive and negative effects. In some cases, friction is necessary and beneficial, such as when it allows us to walk or grip objects. However, friction can also be detrimental, causing wear and tear on surfaces, reducing efficiency, or causing unwanted heat generation.
5. How can friction be reduced or minimized?
Ans. Friction can be reduced or minimized through various methods. One common approach is to use lubricants, such as oil or grease, to create a smooth layer between the surfaces in contact. Another method is to make the surfaces smoother or to use materials with lower coefficients of friction. Additionally, reducing the force pressing the surfaces together can also help to minimize friction.
