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

Acceleration is the rate at which the velocity of an object changes over time.
The rate at which an object's speed changes
is the magnitude of the object's acceleration.
What is the rate velocity changes with time?
Best answer: Acceleration.

acceleration
That's the magnitude of its acceleration.

Not necessarily. Example: an object falling only under the influence of gravity accelerates at a constant rate of about 9.8 meters per square second. Its speed, however, 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.
Acceleration is the rate of change of VELOCITY, not of SPEED. If the velocity changes, there is acceleration. It is enough for the direction to change.
the object's "speed"
Acceleration refers to the rate of change of velocity - how quickly velocity changes. In symbols: dv/dt. When the velocity changes, the speed may, or may not, change. For example, if an object moves in a circle at a uniform speed, its velocity is changing, but its speed is not.
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
No. It's the rate at which a object changes velocity (speed).
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
That is the magnitude (size) of acceleration.

A change in position in a certain amount of time is called motion.
