acceleration
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
accelerationThe rate at which velocity changes is called "acceleration".
velocity
accelerationThe rate at which velocity changes is called "acceleration".
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.
The change in an objects velocity is called acceleration. The formula is:a = F/m where a is acceleration, m is the mass, and F is the force acting on the object.
Velocity
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.
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.
Acceleration
That's the magnitude of its acceleration.
