acctually, you are describing two very similar quantities. th quantity that describes how quickly you change your speed, or how fast you are going is your acceleration, measured in distance per unit of time squared. the quantity that describes how quickly you change your direction is called velocity and it is identical to speed except in the fact that velocityshows how fast you go in a certain direction, or how quickly you change your direction
The quantity that describes how quickly you change your speed is called acceleration. It's usually measured in m/s2 or (m/s)/s. Another definition for acceleration is rate of change of velocity.
D
Acceleration is a vector quantity with both magnitude and direction components. It describes a change in velocity, another vector quantity.The presence of two components distinguishes it from a scalar quantity, like speed, that only has one component (velocity and speed are different).
Its speed.
Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes. Speed is a one dimensional scalar quantity. Velocity is a three dimensional vector quantity describing both speed and direction of motion.

Average speed.
Speed
Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes. Speed is a one dimensional scalar quantity. Velocity is a three dimensional vector quantity describing both speed and direction of motion.
Nwton's First Law: No force , No Change in velocity. The Second Law F=ma says the same thing in that large mass m requires large Force F, is acceleration a is large (change speed quickly)
Agility and speed are the characteristics that allow the body to move and change direction quickly.
It involves the change in velocity, which is a vector quantity, meaning that it is also the change in speed.
speed=distance divided by time........Hewitt describes it as how fast something moves; the distance an object travels per unit of time; the magnitude of velocity !!... and velocity is the speed of an object and its direction of motion ; a vector quantity. SO .....YES!!!!!!!!!!!
The symbol for an average speed is a bold v with a line over the top of it. This is the quantity of change in position over change in time.
