What does negative velocity and negative acceleration mean?
Hereof, what does negative velocity and positive acceleration mean?
That means that the direction of the acceleration determines whether you will be adding to or subtracting from the velocity. Mathematically, a negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity.
Subsequently, question is, can both the velocity and acceleration be negative explain fully with an example? There is no absolute positive or negative velocity or acceleration. For example, let us define the up (away from center of the earth) to be positive.
Keeping this in view, what does negative velocity mean?
A negative velocity means that the object which has the negative velocity is moving in the opposite direction of an object moving at a positive velocity. This is a question of frame of reference. The possibility for the velocity is what makes it different to the speed.
Which is an example of negative acceleration?
So any time you see something slowing down, that's an example of negative acceleration. A car breaking is a common, everyday example of negative acceleration, as is a rolling ball that slows to a stop, and a coin tossed upward (before it starts falling), just to name a few.
