Actually it causes negative acceleration (or decceleration) by slowing things down... some of the kinetic energy of an object is converted to heat when it rubs on something... less energy means less speed.

Remember, just because the word acceleration is used doesn't mean it's speeding something up.
Friction on the tires of your car results in a negative acceleration on your car. It's causing an acceleration, but it's causing your car to slow down, not speed up.

Acceleration is a change in the speed and/or direction (in other words the velocity) of an object.
Friction causes things to slow down which is a form of acceleration

a = F/m
Friction causes a desacceleration. An object pushed with a certain force in a frictionless plane like ice slides faster than one pushed with the same force in a highly frictioned area like dirt.

Because friction allows a moving thing to push against a non-moving thing (tires against the road).

not always but because friction slows down an object, causing its velocity to change and if velocity changes, we have a acceleration.
hope this makes sense to you.

its not it is force times mass = acceleration
