What are the negative effects of friction?
Friction createsheat when ittwo or more objects rub together. This also present in microwaves. Another effect of friction is that it slows down objects thathave friction applied with them.ADVANTAGES OF FRICTIONFriction plays a vital role in our daily life. Without friction we are handicap.1. It is becomes difficult to walk on a slippery road due to low friction.2. We can not fix nail in the wood or wall if there is no friction. It is friction which holds the nail.3. A horse can not pull a cart unless friction furnishes him a secure Foothold.DISADVANTAGES OF FRICTIONDespite the fact that the friction is very important in our daily life, it also has some disadvantages like:1. The main disadvantage of friction is that it produces heat in various parts of machines. In this way some useful energy is wasted as heat energy.2. Due to friction we have to exert more power in machines.3. It opposes the motion.4. Due to friction, noise is also produced in machines.5. Due to friction, engines of automobiles consume more fuel which is a money loss.
What is rolling friction and what does it do?
In general rolling friction is any friction specifically related to the rolling motion. The friction on the axle to hub bearing, the tire flexing, the tire tread on the surface of the road and so on.
Does friction speed up an object?
Friction does not speed up an object; it creates drag and slows it down.
Effect of speed on the force of friction?
Friction is independent of speed once an object is moving since faster does not mean more friction.
What is force called rubbing away?
Friction is the force produced when two objects are rubbed. Rough surfaces exhibit more friction while smoother surfaces tend to be almost frictionless.
Describe a situation in which static friction is useful?
to hold a car on a curved driveway
Describe 3 examples where low friction is not useful?
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.
Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
Is one way that friction is useful?
stopping cars Friction is useful to start a fire with sticks.
Is friction useful?
yes friction is very useful because it help objects not to slide or slip
Is friction useful with computers?
No Friction Runes Computers
When can friction not be useful in a boat?
the friction from pushing the hull through the water is not useful as long as you're travelling.
What three ways can friction be useful?
friction is useful for: you to walk It is needed for braking Can be used to produce heat
When is a high friction useful?
It can be useful when a ball is catching
Why are tyres useful friction?
how does friction help car tyres?
When is high friction useful?
High friction is useful for lots of things, like a goalkeeper's glove. The more friction there is between the glove and the ball, the easier it is to get a hold of it.
When Is Friction Useful and When Is Friction Not Useful?
Friction is useful when you are trying to stop a car, but not useful in the pistons of a car's engine (It makes them less efficient).
