what is the relationship between velocity and acceleration give an example?

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.

Acceleration is defined as the time derivative of the velocity; if the velocity is unchanging the acceleration is zero. Velocity is a vector, speed is a scalar magnitude of the vector. If the velocity vector changes direction you can have constant speed (not velocity) with a non-zero acceleration.

Terms in this set (22) Acceleration is increasing or decreasing speed or changing direction, whereas velocity is how much distance you cover in a given amount of time. What is the difference between constant velocity, instantaneous velocity and average velocity? Give an example of an object with constant acceleration.

Velocity is the rate at which your displacement is changing; it's how fast you're moving, and in what direction. And acceleration is the rate at which your velocity is changing, measured in meters per second per second (or meters per second squared).

Acceleration. This is a change in velocity per time. Average. This is an object's velocity during a specified interval of time.

Velocity is speed with a direction, so distance over time with a specific direction. And acceleration, the king of them all, is distance over time squared, aka the rate at which velocity changes. Whether you are speeding up, slowing down, or changing directions, you are changing your velocity and thus, accelerating.

Newton defined the relationship between force and speed with the formula, F = ma, where a is the acceleration in speed. Acceleration is the rate of change of velocity. Velocity has two (2) components, speed and direction. So the force can result a change in speed of direction, both in the direction of the force.

Acceleration is the rate of change of an object's velocity. Acceleration is a vector quantity, requiring both a magnitude and a direction. ... Velocity changes if the direction of travel or speed changes. Even if the object is moving at a constant speed, the object can be accelerating if the direction of travel changes.

The crucial difference between velocity and acceleration is that velocity is variation in position of the object in a particular direction in unit time. On the contrary, acceleration is variation in velocity in a certain direction per unit time.

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.

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)

Acceleration, we know, is the rate of change of velocity with time. Now we know that the more force we apply , the more will be the increase in velocity of the body initially at rest, thus we can conclude that Force is directly proportional to Acceleration.

By definition, acceleration is the first derivative of velocity with respect to time. Take the operation in that definition and reverse it. Instead of differentiating velocity to find acceleration, integrate acceleration to find velocity. This gives us the velocity-time equation.

Acceleration is the derivative of velocity. Integrate acceleration to get velocity as a function of time. We've done this process before. We called the result the velocity-time relationship or the first equation of motion when acceleration was constant.

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.

If the velocity was previously zero, and still is zero, then the acceleration is zero. If there was previously a non-zero velocity, but the velocity is now zero, then the acceleration is the change in velocity divided by the change in time.

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time. Movement can be shown in distance-time and velocity-time graphs.
