FAQs on Friction & Its Types Video Lecture - Physics for JAMB

 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 acts in the opposite direction to the motion or intended motion of the object.
 2. What are the types of friction?
Ans. There are four main types of friction: static friction, kinetic friction, rolling friction, and fluid friction. Static friction occurs when an object is at rest and trying to be moved. Kinetic friction occurs when an object is already in motion. Rolling friction occurs when an object rolls over a surface. Fluid friction occurs when an object moves through a fluid, such as air or water.
 3. How does friction affect motion?
Ans. Friction affects motion by opposing the motion of an object. It creates resistance, making it harder for an object to move or maintain its motion. Friction can cause objects to slow down, stop, or change direction.
 4. What factors affect the amount of friction?
Ans. The amount of friction between two objects or surfaces is affected by several factors. These include the nature of the surfaces (rough or smooth), the force pressing the surfaces together, and the presence of any lubricants or substances between the surfaces.
 5. How can friction be reduced?
Ans. Friction can be reduced by using lubricants, such as oil or grease, between two surfaces. Lubricants create a thin layer that separates the surfaces and reduces the friction between them. Additionally, using smoother surfaces, reducing the force pressing the surfaces together, or using wheels or ball bearings can also help reduce friction.
