Friction is useful because it helps objects grip and move against each other. It allows us to walk, drive cars, and hold objects without them slipping from our hands. However, excessive friction can also cause wear and tear on objects.
A common example of useless friction is rubbing your hands together when they are already warm. This generate unnecessary heat and does not provide any practical benefit.
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.
