acceleration
accelerationThe rate at which velocity changes is called "acceleration".
variable velocity can be defined as a moving body whose velocity changes with time
Constant rate of change mean a variable changes constantly over the same time period. Best example is gravity and velocity, which are defined as v=at, where a=gravity=32.2 ft/s2. if you drop an object, after 1 sec, the velocity =32.2 ft/s. After 2 seconds, v= (32.2)*(2)=6.4.4 ft/s, and so on... So, even though gravity is constant, the rate of change in velocity is it doubles every second.
"Rate of change" means how quickly something changes. Examples in physics include a speed as a rate of change of position - if your position changes 10 meters every second, then that (10 meters/second) is your rate of change of position, or your velocity. Or if your income increases by a thousand dollars a year, then that's the rate of change of your income - how quickly your income changes.
Velocity is defined as speed in a certain direction, or vector.

Changes.
Velocity is defined as a vector quantity representing both speed and direction. Acceleration is defined as the rate at which velocity changes. The acceleration of an object changes when it is acted upon by an unbalanced force.
The formula for velocity is velocity = distance / time. It represents the rate at which an object changes its position.
That rate at which the velocity of an object changes is known as the acceleration of said object. It can be defined mathematically as a=v/t where a=acceleration, v=the change in velocity, and t=the time in which this change in velocity occurred.
An acceleration index is a vector quanity, which is defined as the rate at which a defined object changes its velocity.
Whenever the velocity changes. Acceleration is defined as the rate of change of velocity with respect to time (in symbols, dv/dt), that is, how fast does the velocity change.
'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.
Acceleration and it is defined as the rate of change of velocity with time.
Rate of change of velocity (in advanced mathematics, they call that the derivative of velocity). In other word, how fast the velocity changes. Commonly measured in (meters / second) / second, which is usually written as meters / second2.
Velocity changes are referred to as acceleration.
