andrevdh said:The change in the velocity is the velocity vector that when it is added to the initial velocity one would get the final velocity. That is the initial velocity vector plus the change in the velocity vector gives one the final velocity vector.
To calculate the change in velocity of a van, you need to know its initial velocity and its final velocity. Then, subtract the initial velocity from the final velocity to get the change in velocity.
The formula for calculating change in velocity is: ∆v = vf - vi, where ∆v is the change in velocity, vf is the final velocity, and vi is the initial velocity.
Change in velocity is a measure of the difference between an object's initial velocity and its final velocity. It can be positive or negative, depending on whether the object is speeding up or slowing down.
Change in velocity can be used to measure an object's acceleration by dividing it by the time it took for the change to occur. This gives us the average acceleration of the object over that time period.
The change in velocity of a van can be affected by various factors such as the force applied to the van, the mass of the van, and any external forces acting on the van, such as friction or air resistance.
