Friction can be helpful in many ways.
You can start a fire by rubbing two sticks together
The brakes in your car rely on friction to slow you down
Friction of the air in our atmosphere creates lift around the wings of an airplane and also allows airplanes to turn. (Wings have no use in space where there is not atmosphere)
You can rub your hands together in cold weather and use the heat from the friction to warm them up.
friction is very useful but it has its own disadvantages. Friction can be useful in producing heat (such as starting a fire without matches) or providing a grip on slippery surfaces (such as in specially designed slick-resistant shoes).

What are some ways friction is helpful and some ways it is harmful?
it can give us warmth

Name some ways that friction can be helpful and some ways it is harmful?
Friction is helpful in situations like when you are standing on a hillside. Static friction between your shoes and the surface are stopping you from slipping. Friction is not helpful in situations like when you are pulling something heavy. Some of the energy you are putting into pulling is going into heat from kinetic friction and making your job more difficult.
When is decreased friction helpful?
Decreased friction is very helpful in working machinery, because friction causes wear and tear.Mainly its very helpful in moving parts. Decreased friction is also helpful in electric cables and wires, as reduced friction reduces energy loss via heat.
What is a harmful and helpful example of friction?

In what ways can friction be helpful?
Friction is necessary for wheels to rotate and nails to keep in walls.
What are the helpful ways of friction?
Without friction, we couldn't walk or grip onto anything.

Name 2 ways that friction is helpful when riding your bike?
Friction lets the drive wheel push you forward, and allows your brakes some bite. Friction make it possible to hold on to the bars. Friction lets you steer.

How can friction be increased?
There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.

When friction is not helpful?
Friction can be helpful and not helpful it is not helpful when you are running because it slows you down hope that'll help!!!! ;)

Where friction is helpful?
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
