WebMay 31, 2011 · 2 Answers. Integrate the acceleration of each axis then add together the velocity vectors, and finally take the magnitude. You now have speed. Look up "adding together vectors" in relation to maths. Assuming you have the 3D velocity vector (x, y, z), the speed can be calculated using Pythagorus' theorem: speed = sqrt (x^2 + y^2 + z^2).

WebJan 24, 2024 · Speed: Velocity: Speed is the rate of change of position with time. Velocity is the rate of change of position with time in a particular direction. Speed is a scalar quantity. Velocity is a vector quantity. Speed can only be positive. Velocity can be positive, zero, or negative. Speed can be equal to or more than velocity. uloric with kidney diseaseWebLet's say the object was thrown up at 29.4 m/s. So since the object was thrown up which a positive direction it is initially traveling at + 29.4 m/s. After 1 second we know that the velocity changed by - 9.8 m/s so at this point in time the object is traveling at a velocity of (+ 29.4 m/s) + (- 9.8 m/s) = + 19.6 m/s. thomthomanWebFeb 25, 2012 · Use the same technique: calculate the target's motion in the x, y, and z directions.
