Vectors delta velocity calculations

In summary, the conversation discusses waves originating from point A and B, which can be treated as vectors and are velocity-direction-dependent. It took t2 time for the wave from point B to reach A, and t2 time for the wave from point B to reach A. The only known variables are t1 and t2, and the question posed is whether there is a way to calculate \Delta v, which depends on the constant distance between A and B. It is mentioned that if this distance is unknown, \Delta v cannot be calculated.

Hello,

Two waves originated from point A and point B, waves are 'velocity-direction-dependent', can be treated as 'vectors', it took t2 time for the wave from point B to reach A, and it took time t2 for the wave from point B to reach A.

Given the fact the two vectors have the same 'magnitude', and only the t1 and t2 are known is there a way to calculate delta velocity?



A>>>>>>>>>>> B, in t1 time
B>>>>>>>>>>> A, in t2 time

Distance between A and B is constant, and only known variables are t1 and t2, is there a way to calculate Δv?


thank you!

Distance between A and B is constant

Is it a known constant value? - or it is an unknown value, just known to be some constant?

If the distance from B to A is d, then the first wave, taking t1 to go from B to A, has speed d/t1. The second wave, taking t2 to go from B to A, has speed d/t2. The "[itex]\Delta v[/itex]" is d/t1- d/t2= d(t2- t1)/t1t2.
If you do not know the distance from B to A, then you cannot calculate [itex]\Delta v[/itex].
 

1. What is a vector in terms of delta velocity calculations?

A vector is a quantity that has both magnitude and direction. In delta velocity calculations, vectors are used to represent changes in velocity over time.

2. How is a delta velocity vector calculated?

A delta velocity vector is calculated by subtracting the initial velocity vector from the final velocity vector. The resulting vector represents the change in velocity over a specific period of time.

3. Can delta velocity vectors have negative values?

Yes, delta velocity vectors can have negative values. A negative value indicates a decrease in velocity, while a positive value indicates an increase in velocity. The direction of the vector will also indicate the direction of the change in velocity.

4. What units are used to measure delta velocity vectors?

Delta velocity vectors are typically measured in meters per second (m/s) or kilometers per hour (km/h). However, any unit of distance over time can be used, as long as it is consistent throughout the calculation.

5. How are delta velocity vectors used in physics?

Delta velocity vectors are used in physics to calculate the change in an object's velocity over time. This is important in understanding the acceleration and movement of objects in space, as well as in analyzing the forces acting on them.
