what is a relationship between velocity and acceleration?
61168
Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.

Because acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is also a vector quantity. Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

Velocity is the displacement by an object per unit time. Acceleration is the change in velocity per unit time. So, a body in constant speed is said to have zero acceleration.

Acceleration is simply a rate of change of velocity. So the magnitude tells you, how quickly velocity changes.

Acceleration is the rate of change of velocity. It is the amount that velocity changes per unit time. This is when: acceleration (α) is measured in metres per second squared (m/s²)

Acceleration is the change in velocity, not the velocity itself; therefore, an object can have zero velocity but not zero acceleration because the velocity will be changing.
66595
Rate of change of velocity of an object is known as acceleration of that object. If acceleration is constant then it means velocity is changing ( increasing ) uniformly in equal interval of time. Thus by simple reason, velocity keeps increasing uniformly when acceleration is constant.

Acceleration is the change in velocity per time. Acceleration, then, is the change in my velocity per unit time. ... Thus, our acceleration is 4 m/s/s in the +x direction. So, acceleration is the change in velocity per time. Speed is the magnitude of velocity.

So, the acceleration is the change in the velocity, divided by the time. Acceleration has a magnitude (a value) and a direction. The direction of the acceleration does not have to be the same as the direction of the velocity. The units for acceleration are meters per second squared (m/s2). a = acceleration (m/s2)

From such a graph acceleration can be determined as the change in velocity divided by the change in time in a given interval. ... When you know there was a constant acceleration or a nearly constant acceleration, the average velocity will be the middle velocity between the initial velocity and the final velocity.

Explanation: Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).

Another formula, acceleration (a) equals change in velocity (Δv) divided by change in time (Δt), calculates the rate of change in velocity over time. This formula may be written a = Δv ÷ Δt. Since velocity includes both speed and direction, changes in acceleration may result from changes in speed or direction or both.

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time.

Velocity is vector: That means that going in one direction in velocity is not the same as going in the opposite direction. ... Acceleration is rate of change of Velocity: How quickly your velocity is increasing or decreasing. It is measured in meters per second per second, or m/s/s.

Acceleration is defined as the time rate of change of velocity. Since velocity has both magnitude and direction, so does acceleration. ... So the magnitude of acceleration is the magnitude of the acceleration vector while the direction of the acceleration is the direction of the acceleration vector.

Velocity is the rate of change of displacement. Acceleration is the rate of change of velocity. Velocity is a vector quantity because it consists of both magnitude and direction. ... These are the differences between velocity and acceleration.

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
