What are 3 factors that affect friction?
The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies. Question 4: What is streamlined shape explain with example?
What are the factors affecting friction Class 8?
There are three factors that can directly affect friction between two bodies or surfaces.
- Nature of area.
- Weight of the bodies and.
- Area of contact.
What are the 2 factors that affect the friction force between two surfaces?
Answer and Explanation: The factors that affect the friction between two surfaces are the weight of the object and the coefficient of friction of the surface.
What are the factors affecting friction Class 8 Brainly?
Answer
- surface Roughness.
- The weight on the surface.
- The texture of the surface.
- The angle of the surface.
- Adhesion.
What are effects of friction?
Friction reduces the speed of the moving objects and it even stops the motion of the object. Friction between the objects produces heat. This results in the wastage of energy in the machines. There will be wear and tear of the machine parts due to friction.
What causes of friction?
Friction is caused due to the irregularities on the two surfaces in contact. Even the smoothest surfaces have minute irregularities in them and these irregularities of the two surfaces interlock into each other and create friction.
What are the types of friction class 8?
There are four types of friction: static, sliding, rolling, and fluid friction (Air/Viscous friction). Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases.
What are the causes and effects of friction?
Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.
What are the different effects of friction explain with examples?
Answer: Friction force give their effect on a moving object in opposite direction. For example- when we are pedaling continuously the cycle, it moves and when we stop pedaling the cycle begins to slow down because frictional force opposes to cycle.
What are the causes and effect of friction?
How does friction affect speed?
Friction always opposes the motion and reduces the speed at which the object moves on the surface. It will turn some of the kinetic energy of an object into heat energy, thereby reducing the speed.
What are the five causes of friction?
Causes of friction
- Interlocking of irregularities.
- Chemical bonding.
- Electrostatic interaction.
- Electromagnetic interaction.
- Pressure.
What are the factors affecting force?
(i) The magnitude of the force applied. (ii) The distance of line of action of the force from the axis of rotation.
On which factors does friction depends Class 9?
Answer: The force of friction is directly proportional to the weight of the body sliding over the surface. The force of friction also depends on the nature of the surfaces in contact.
Who is the father of friction?
Answer. Proffesor David Tabor is called the father of friction.
How can we reduce friction?
Methods for Reduction friction:
- Make the surfaces little more smoother.
- Lubrication is another way to make a surface smoother.
- Make the object more streamlined.
- Reduce the Normal force acting between the surfaces in contact.
- Reduce the contact between the surfaces, so that less number of bonds will be formed.
