to hold a car on a curved driveway
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.
stopping cars Friction is useful to start a fire with sticks.
An example of not useful friction is the friction between the tires of a car and the road surface when trying to accelerate. This friction wastes energy in the form of heat and wears down both the tires and the road, without serving a beneficial purpose in this context.
Yes, friction is useful because it helps to provide traction for walking and driving, prevents objects from sliding off each other, and allows us to grip objects. However, excessive friction can also lead to wear and tear on surfaces.
It cant run electrical things with it, you kind of dont expect it to happen it just happens. Thier is nothing you can really do. Once friction builds up it can create a positive charge or a negative charge , so when the friction is built up it can shock you at any time. There isnt really a time you can say,it just happens at any time when the friction builds up and its ready to discharge.
When a tire or anything needed to move matter requires traction.
When taking algebra tests.

Brakes are meant to have a lot of friction and it's useful.
You can move things with static electricity!
No Friction Runes Computers
the friction from pushing the hull through the water is not useful as long as you're travelling.
It can be useful when a ball is catching

Friction 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. When we move on ice, it becomes difficult to walk due to low friction of ice.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.
