It keeps the parachute slow.
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.
Friction is useful because it provides traction for walking and driving, allowing us to move on surfaces without slipping. It also helps us to grip objects and manipulate them with our hands. Additionally, friction generates heat, which can be harnessed in machines for various purposes.

It is useful
Friction is useful when you are trying to stop a car, but not useful in the pistons of a car's engine (It makes them less efficient).
