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

∙ 12y agoThe 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.

What is the defintion of velocity?
What phrase describes speed A. A quantity with direction only B. A quantity with no units C. A vector quantity D. A scalar quantity?
D
What type of quantity is acceleration?
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).
What property of a wave describes how quickly it moves?
Its speed.
When an object's speed change does its velocity change?
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.

What is the quantity of miles per hour describes a motion known as?
Average speed.
What word describes the ability of vampires to move quickly?
Speed

Which of Newton's Laws describes that a large massive body requires a large force to change speed quickly?
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)
Which fitness skill combines with strength and speed?
Agility and speed are the characteristics that allow the body to move and change direction quickly.
Acceleration involves a change in what?
It involves the change in velocity, which is a vector quantity, meaning that it is also the change in speed.
Does change in the velocity of an object always indicate a 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!!!!!!!!!!!
What is the symbol for speed?
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.
