Question

types of friction Related:  NCERT Solutions - Friction, Science, Class 8

Answer

Static, sliding, rolling and fluid friction

Answer

Rolling friction, sliding friction and static friction

Answer

There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rollingfriction occur between solid surfaces. Staticfriction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluidfriction occurs in fluids, which are liquids or gases.

Answer

Types of Friction
Friction is a force that opposes the relative motion of two surfaces in contact. It plays a crucial role in our daily lives, affecting how we walk, drive, and interact with various objects. There are several types of friction, each defined by the nature of the surfaces involved and the conditions under which they interact.
1. Static Friction
- Static friction is the force that keeps an object at rest from moving.
- It acts when there is no relative motion between the surfaces.
- It must be overcome to initiate movement and is generally higher than kinetic friction.
2. Kinetic Friction
- Kinetic friction, also known as dynamic friction, occurs when two surfaces are sliding against each other.
- It is usually lower than static friction, making it easier to keep an object moving once it has started.
- The coefficient of kinetic friction is often used to quantify this force.
3. Rolling Friction
- Rolling friction occurs when an object rolls over a surface, such as a wheel or ball.
- This type of friction is generally much less than static or kinetic friction.
- It is essential for the movement of vehicles and machinery.
4. Fluid Friction
- Fluid friction happens when an object moves through a fluid (liquid or gas).
- It depends on the object's shape, speed, and the fluid's viscosity.
- Common examples include air resistance experienced by a moving car or a swimmer moving through water.
5. Limiting Friction
- Limiting friction is the maximum frictional force that can be exerted before an object starts to move.
- It is critical in determining the conditions under which an object will start sliding.
Understanding these types of friction helps in various applications, from engineering to sports, enhancing our ability to design systems that effectively manage these forces.

Answer

There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest.
