We want a lot of friction when we need to slow down or stop objects in motion, like when braking a car or walking on a slippery surface. More friction provides more resistance to movement, helping to prevent sliding or slipping.
Having a lot of friction can be bad when you want smooth motion between two surfaces, as it can cause heat, wear, and energy loss. In some cases, high friction can also lead to difficulties in moving objects or machinery.
Lots of friction is needed in car brakes to slow down or stop the vehicle effectively, in shoe soles to provide traction and prevent slipping, and in rock climbing equipment to secure climbers on the rock surface.
Rough surfaces tend to provide a lot of friction due to the increased amount of contact between the two surfaces, which leads to more interaction and resistance to sliding. Examples include sandpaper, concrete, and asphalt.
Wood generally has a moderate level of friction due to its rough texture and absorbent nature. The amount of friction can vary depending on the type of wood, its finish, and the surface it is in contact with.
Activities like driving, exercising, and collaborating with others would benefit from less friction.

Friction is applied, by making the surface of whatever you want to slide across it (the thing you want to apply friction to) is really rough. You can inscrease, and decrease the amount of friction acting on an object by changing the texture, material and smoothness of the surface. Smoother surfaces don't apply much friction to objects, and rougher surfaces apply a lot. An example of this, is Wellington Boots. They have rough underneaths, so you don't fall over - they apply a lot of friction.
rough materials can generate a lot of friction
Brakes are meant to have a lot of friction and it's useful.
If you want to swim faster, then decreasing friction would help you with that - Less friction means you glide easer through the water. If you want a more efficient workout then increasing friction would help you with that. If you were to put a track suit on before entering the water you'd have to work a lot harder for each lap in the pool.
what are some objects that have a lot of friction
You want less friction. Then you will go faster.
In the bearings, where you want as little friction as possible.

I sense a lot of friction between Israel and Gaza. == ==
It stops the water from going through your hair. That would cause a lot of friction. Friction slows you down a lot.
