Finding position from velocity with integration

In summary, integration is a mathematical process used to find the original function from its derivative. It helps in finding the displacement function from the velocity function, which is useful in determining an object's position. However, there is a difference between position and velocity, as position is the location of an object while velocity is the rate of change of an object's position over time. While velocity alone cannot determine position, integration is needed to find the position function. Integration is commonly used in real-life scenarios such as physics, engineering, and economics to find position from velocity. However, there are limitations to using integration, including the need for a continuous and well-defined derivative and the potential for errors in measurement and calculation.

EDITED:

My answer was right, the answer of the software was wrong :D !

So this thread should be deleted.

THANKS!

position vector = [at - (bt^3)/3 + v_x(0)]i + [(ct^2)/2 + v_y(0)]j
position vector = [at - (bt^3)/3 + a]i + [(ct^2)/2]j
This however is the wrong answer and I don't know understand why?

out?
Your initial conditions for position are not your initial values for velocity.
 

1. How does integration help in finding position from velocity?

Integration is a mathematical process that helps in finding the original function from its derivative. In terms of finding position from velocity, integration helps by finding the displacement function from the velocity function.

2. What is the difference between position and velocity?

Position is the location of an object in relation to a reference point, while velocity is the rate of change of an object's position over time. In other words, position tells us where an object is located, while velocity tells us how fast and in what direction it is moving.

3. Can position be determined from velocity alone?

No, position cannot be determined from velocity alone. Velocity only tells us about the rate of change of an object's position, but it does not give us the actual position. Integration of the velocity function is needed to find the position function.

4. How is integration used in real-life scenarios to find position from velocity?

Integration is used in many real-life scenarios, such as in physics, engineering, and economics, to calculate position from velocity. For example, it is used in calculating the position of a moving car, the displacement of an object under the influence of gravity, and the change in stock prices over time.

5. Are there any limitations to using integration to find position from velocity?

Yes, there are limitations to using integration to find position from velocity. One limitation is that the velocity function must be continuous and have a well-defined derivative. Additionally, integration can only give us an approximate position, as it is subject to errors in measurement and calculation.
