The rate at which velocity changes over time is known as acceleration. In calculus, acceleration is the derivative of velocity with respect to time.


No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.

An object accelerates if its velocity changes. More precisely, "acceleration" is the rate of change of velocity (how quickly velocity changes), or in symbols, dv/dt.


Velocity is change in position, or displacement, over time.


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.


No. It's the rate at which a object changes velocity (speed).


That's the magnitude of its acceleration.


That's the magnitude of its acceleration.


That's the magnitude of its acceleration.


Velocity is defined as the rate at which an object changes its velocity; therefore if there is zero velocity then acceleration is neutral as well.


That's simply called a change in velocity. On the other hand, the rate of change in velocity - how quickly velocity changes - is called acceleration.


Position is the place where an object is located. Speed is the rate at which position changes. Velocity is the speed and direction of motion. Acceleration is the rate at which velocity changes, and the direction of the change. So you could say that acceleration is the rate at which (the rate at which position changes and the direction) changes, and the direction of the change.


The rate at which velocity changes is known as the acceleration of an object.Calculating acceleration, given velocity can be achieved with the formula:acceleration = change in velocity / change in time



Acceleration is the rate of change in velocity. (Velocity is speed+direction, it is a vector as well as acceleration). F=ma, where a is in ms^(-2).


Velocity is the rate at which location changes, and the direction in which location changes. Acceleration is the rate at which the size of velocity changes, and the direction in which velocity changes.


'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 is the rate at which an object's velocity changes over time.


Acceleration is the rate at which an object's velocity changes over time.


The rate at which velocity changes in time is called acceleration.


accelerationThe rate at which velocity changes is called "acceleration".


Velocity is speed with a direction. Acceleration is the rate at which velocity changes, just as velocity is the rate at which position changes (and jerk is the rate at which acceleration changes).


The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".


The rate of which something changes its velocity is the acceleration. A common mistake is to think that something moving fast is accelerating, but it's only accelerating if the velocity of that object is changing.
