Friction always works against the velocity and so it always works to slow down an object.
yes friction is very useful because it help objects not to slide or slip
Wheels reduces the friction because to improve the speed of the machines. friction can be reduced with the help of the lubricants.
friction slows us down if it wasn't for friction everyone would be slipping everywhere
Friction
Streamlining is a way to help an item travel faster. Friction is nearly the exact opposite, as it will slow an item down.
Speed is how fast something is moving. When to things are traveling at the same speed and rubbing together, they can cause friction.
Stop or slow an objects motion.

Friction
Friction is able to help you run because you have the ability to slow down, stop, or even go faster. Without friction you wouldn't be able to stop running.

"Air Pressure affect moving bodies by highly air pressure bump into a less dense object then acceleration functions then turn by speed and inertia where alll things stop called inertia help by friction."
Ball bearings
it can help to slow down a rock that has been thrown hard
Yes it does. Some have shocks(which help take in friction that helps you run faster)
