there are many advantages of friction. It helps us in driving, walking, writing, holding objects, etc.
Helps in wolking e.g slipary places
Helps in stoping objects e.g cars
It also heips fire production(2metals rubbed together gives out sparks
leading to fire).
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
what is the advantages of friction
friction is a natural force
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.
No, the ideal is without friction.
There are many reasons why friction is an advantage to human motion. Friction helps humans to stop when they need to stop.
Advantage of friction photo
rubbing your hands together produce heat that is friction.
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
if it is an advantage then it can't be bad
is gripping a pipe with a stillson wrench an andvantage or a disadvantage of friction?
In real machines, there is always friction that reduces the efficiency of the machine.This reduces the mechanical advantage because some of the input force has to be used to overcome the force of friction in the machine.To reduce friction in the machine, you could add a lubricant such as oil.
ignoring friction or ideal mechanical advantage
Advantage-we can write. Disadvantage- hard to move objects
