# What is the link between velocity and acceleration?

I'm not quite sure what you're asking, but.....

An object that is accelerating simply means that that object's velocity is changing. It can be increasing (positive accel.) or decreasing (negative accel.). If the acceleration is zero, that means the velocity is constant.

(Keep in mind that these are all vector quantities, so they will have directions as well as magnitudes, and the positive/negative may be reversed.)

Rate of change of velocity is called acceleration. The mathematical link is: acceleration a=dv/dt where v is the velocity. It's a derivative of v with respect to time t.

The relationship between velocity and acceleration is that they both have rate of changes.

Acceleration is the rate at which velocity changes with time, where as velocity is speed with a direction.

Velocity is distance over time, Acceleration is velocity with a direction.

Velocity is the rate of change of distance with time, acceleration is the rate of change of velocity with time.

Uniform velocity is velocity unaffected by acceleration. Variable velocity is velocity affected by acceleration. Lauren "Physics above all!"

Velocity is speed with a direction. Acceleration is the rate at which velocity changes, just as velocity is the rate at which position changes (and jerk is the rate at which acceleration changes).

If there is acceleration (uniform or otherwise, but non-zero acceleration), the velocity changes. Constant velocity means that the velocity does not change.

-- 'Velocity' is the rate at which position is changing, and the direction of the change. -- 'Acceleration' is the rate at which velocity is changing, and the direction of the change.

Acceleration is the change in velocity over a period of time. a = v/t

Acceleration is a change of velocity (per time unit).Acceleration is a change of velocity (per time unit).Acceleration is a change of velocity (per time unit).Acceleration is a change of velocity (per time unit).

Velocity is the rate of change of position; acceleration is the rate of change of velocity; jerk is the rate of change of accelerationSee related link below for information on "Jerk"

Velocity is a measure of speed at any one instant and acceleration is a measure of change in speedAcceleration is defined as the rate at which velocity changes.Constant velocity doesn't change, so it's a condition of zero acceleration.

Acceleration is a change in velocity. More precisely, to get acceleration, you divide the change in velocity, by the time that passed.Acceleration is a change in velocity. More precisely, to get acceleration, you divide the change in velocity, by the time that passed.Acceleration is a change in velocity. More precisely, to get acceleration, you divide the change in velocity, by the time that passed.Acceleration is a change in velocity.

No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.

An object moving with uniform acceleration has a uniform change in velocity over time, and its velocity-time graph will be a straight line with either a positive or negative slope. An object moving with no acceleration has constant velocity, and its velocity-time graph will be a straight, horizontal line with zero slope. Refer to the related link for illustrations.

your seed,velocity,and acceleration will be slow When you brake, your acceleration increases (!), your velocity decreases (and in this case, there is no difference between velocity and speed). Negative acceleration increases when braking a moving bike.

Velocity is the change in displacement in a unit time in a specific direction. Speed is the magnitude of velocity and has no direction. Acceleration is the change in velocity in a unit time.

Avg velocity is the speed you are going. Constant acceleration is the rate you increase your speed. = =

Velocity . . . what speed and direction something is moving. Acceleration . . . how fast the speed and/or direction of its motion are changing.

Acceleration is the rate of change of the magnitude of velocity and the direction in which the velocity changes.

Regarding their magnitudes . . . Acceleration is the time rate of change of velocity. Regarding their directions . . . There's not necessarily any relationship between the two.
