Acceleration is constant.
Increase of velocity over a period of time is called acceleration.
Literally the definition of acceleration.
Acceleration is a change in velocity over a period of time.
That is called "acceleration". In symbols, that would be a = dv/dt; this means change in velocity divided by change in time, for a small time period.
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
ACCELERATION- A measure of the rate at which a defined amount of matter increases/decreases its velocity, measured in change in velocity over a period of time.=========================Answer #2:Acceleration is any change in the speed or direction of motion.
Acceleration is the rate at which velocity changes. When velocity is decreasing, sometimes the word "deceleration" is used instead. Acceleration and deceleration describe generally how velocity can change. Keep in mind that things can get a little more complicated than just speeding up or slowing down. For example, in an elevator going up, you can feel increased G force resulting from acceleration upward, and you can also feel increased G force if the elevator is in free-fall and it decelerates.Acceleration is mathematically described as:a = dv/dtwhere dv is the change in velocity over a specific period dt.The rate at which velocity changes is either acceleration or deceleration, and it is expressed by: a = Δv/t acceleration = change in velocity / time takena = F/m acceleration = resultant force / massHowever, since velocity is a vector quantity (it has both value and direction), acceleration also is a rate at which direction changes when velocity is constantThe rate of change in velocity is known as acceleration.
Dividing change of velocity by the time it takes to change the velocity. If acceleration is not constant, this will give you the average acceleration during the period; to get the instantaneous acceleration, you have to take the derivative of the velocity.

A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
