The definition of rate of rate of change of velocity is Velocity is the rate of change of the position of an object, equivalent to a specification of its speed and direction of motion, e.g. 60 km/h to the north. Velocity is an important concept in kinematics, the branch of classical mechanics which describes the motion of bodies.

∙ 9y agoRate means per unit of time. 5 miles per hour is a rate because it is expressed as distance per unit of time. Acceleration is a simple rate of change -- the rate changes. Hmm, maybe I look too deeply. Perhaps all that is meant is rate. **So rate of change means rate.** The rate of change of distance is the rate called speed (or sometimes velocity).

Rate of change of the velocity of an 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".
What is the formula for acceleration?
a=dv/dt. By definition, acceleration is the rate of change of velocity. In mathematical notation, it is given as the formula stated above. Two special cases: 1. When acceleration is constant: The rate of change is a constant. Therefore, it can be calculated by: a=(vf - vi) / t where a is acceleration vf is final velocity vi is initial velocity and t is time taken 2. When velocity is constant: Velocity is not changing. The rate of change of velocity is zero. Acceleration has to be zero. * * * * * Note that velocity and acceleration are both VECTORS. Therefore, an object going round in a circle, at CONSTANT speed, has velocity and acceleration that are changing all the time - because the direction of motion is changing.
What describes velocity?
two things that describe velocity is distance and time.
What is the equation for force in terms of momentum?
Force is defined as mass times acceleration.Momentum is defined as mass times velocity. Acceleration is defined as the rate of change of velocity. Velocity is defined as the rate of change of location in space.
What is the value of acceleration for a body?
Acceleration means how fast the body's velocity changes - in symbols, dv/dt. Average acceleration during a certain time is equal to (change in velocity) / (time elapsed). Since you are dividing a velocity by a time, the standard unit for acceleration is (meters / second) / second, but this is normally written as meters / second squared.
Why does velocity represents rate of change of displacement?
Because that is the definition of velocity
Rate of change of velocity?
That's the definition of 'acceleration'.
What is the physics definition of velocity?
In physics, velocity is the measurement of the rate and direction of change in the position of an object.
Another definition for acceleration?
Another definition for the word "acceleration" is "the rate of change of velocity per unit of time."
What is rate of acceleration?
The rate of change of velocity. (As velocity is the rate of change of position.)
What is the definition of accerlation?
Rate of change of velocity.i think you mean 'acceleration'anyway here's the definition--noun1.the act of accelerating; increase of speed or velocity.2.a change in velocity.3.Mechanics . the time rate of change of velocity with respect to magnitude or direction; the derivative of velocity with respect to time.
What is the definition of velocity time graph?
The rate of change in velocity in given time. By Suraj Kumar
What is the definition for the rate of motion?
The rate of change of motion is known as acceleration. Acceleration is the change in velocity over change in time. Velocity is the rate of change of position, or change in position over change in time.
Give an operational definition of acceleration?
"Acceleration" doesn't mean "speeding up". It means the rate at which velocity is changing. And "velocity" doesn't mean "speed". It means speed and direction.
What is the definition of zero acceleration?
Zero rate of change of velocity. Straight-line motion at a constant speed.
The velocity of an object is the rate of change of its position What is it?
Velocity is the rate of change of the position of an objec
What is the rate change in velocity?
The rate of change in velocity is known as acceleration.
