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.
if it is an advantage then it can't be bad
Tires skidding on a wet road due to lack of traction. Trying to push a heavy object across a rough surface with a lot of resistance. Rubbing two rough surfaces together, causing heat and wear on the materials involved.
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.
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.
It depends what you want to do with it. Friction generates heat, which can be good (if you are cold), or bad (if you are not). Friction slows down movement, which can be good (if you are about to crash into a tree with your car), or bad (if you need high performance in an engine for instance).
bad friction is when 2 things rub together .
Friction isn't always bad, but when engineers try to avoid or reduce friction, it is because of the energy lost due to friction.
rough materials can generate a lot of friction
Brakes are meant to have a lot of friction and it's useful.
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
what are some objects that have a lot of friction
botch
No friction is not always bad. In fact consider an example of running on wet floor. If there is too little friction it might cause you to slip and slide.
it wears things away
It can be bad when a gymnast is on bars because too much friction between the bars and the hands can cause calluses/skin to rip off and leave the skin raw and/or bleeding. This can make practicing on bars very painful for a gymnast.
