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.

When an object changes speed does its acceleration change?
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.
What changes speed and direction?
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.
Is the rate of change of an object?
the object's "speed"
How can an object be accelerating while traveling at the same speed?
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.
How do speed and velocity relate to acceleration?
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.
Is the rate at which an object changes velocity?
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
Is acceleration the rate at which an object covers a given distance?
No. It's the rate at which a object changes velocity (speed).
What changes as an object moves with a constant acceleration?
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.
When does the speed of an object change?
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.
Does the speed of an object change?
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.
What is the rate at which an object's speed changes per unit time?
That is the magnitude (size) of acceleration.
When an object changes speed does its acceleration change?
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.
What changes speed and direction?
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 rate at which an object changes position is called what?
A change in position in a certain amount of time is called motion.

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.
What is the rate of motion of an object in a linear object?
That is the object's 'speed'.
