Yes, Friction will never speed up an object because friction slows objects down.
An object with mass might approach, but never reach, the speed of light.An object with mass might approach, but never reach, the speed of light.An object with mass might approach, but never reach, the speed of light.An object with mass might approach, but never reach, the speed of light.

Making an object speed up or slow down always requires a force.-- To make the object speed up, apply a force to it in the same directionthat it's moving.-- To make it slow down, apply a force to it in the opposite direction.
An object is accelerating if any of these things are happening . . .-- its speed is increasing-- its speed is decreasing-- its direction is changing.The object may be accelerating even if its speed isn't changing.Acceleration does not mean "speeding up".

You may be thinking of drag instead of friction. Friction between the floor and your foot increases your speed.
An object can only slow down, speed up, or change direction, if there is a net force acting on the object.
terminal speed
Potential energy, which can be released as kinetic energy. Kinetic energy not the build up of speed in a moving object.
The word object is a very general term. A photon is also an object, and it does travel at the speed of light. But it never travels at any other speed, so it doesn't "gain" that speed. If we were to ask about objects made of atoms, then the answer is no, they can never accelerate to the velocity of light. They can get arbitrarily close, depending upon how much energy is used to accelerate them, but they can never actually get to the full speed of light.
The speed of the object and its direction of motion.
Friction does not speed up an object; it creates drag and slows it down.

whyh does the sped decreases when an object is thrown vertically up
