You may be referring to Train Train by Blackfoot.
This depends on how you define your axes. Let's assume they're defined as normal (being positive is accelerating, negative is breaking, and for velocity positive is driving forward, negative is driving in reverse). Then of course, you are speeding up. This simply means the train was in reverse, but it's accelerating in the positive direction now.
An object that is accelerating is either speeding up or slowing down. If the acceleration is in the same direction as the velocity, the object is speeding up. If the acceleration is opposite to the velocity, the object is slowing down.
-- speeding up -- slowing down -- curving
acceleration is changes in speed slowing down and speeding up.
When an object is speeding up or slowing down, it is experiencing acceleration. When it is turning, it is undergoing rotation or changing direction.
If you are saying about internet , it is because of your speed.
Slowing down and Speeding up
Speeding up, slowing down, and turning.
When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
changing direction, speeding up, and slowing down
Positive is speeding up and negative is slowing down
Positive acceleration = speeding up. Negative acceleration = slowing down.
