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.
Acceleration means to gain speed. Losing speed is called deceleration.
An object that is accelerating may be slowing down, gaining speed, and changing direction.
In physics, "acceleration" means there is a change of velocity.
yes the acceleration can take a negative value. for example an object with an accleration of -2 ms-2 would be slowing down. However this is normally called deceleration.
slowing down.
its when something is slowing down
An object that is accelerating may be slowing down, gaining speed, and changing direction.
No, when anything is slowing down it is decelerating.
In physics, "acceleration" means there is a change of velocity.
It is decelerating any time it is not accelerating or is stopped. Decelerating means slowing down.
Could be bad u-joints in the driveshaft.
You may be referring to Train Train by Blackfoot.
Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.
One tire has a belt separation.
No. Negative acceleration simply means it is accelerating in a particular direction.
yes the acceleration can take a negative value. for example an object with an accleration of -2 ms-2 would be slowing down. However this is normally called deceleration.
Yes it has negative acceleration, which is acceleration in the opposite direction of travel. It is called deceleration.
Could be a turbocharger, or a low oil level in a manual transmission causing it to "howl".
