Calculating velocity of a particle if distances are constant
May 17, 2025 · In that case, A and B are satellites of C, and when the three particles become collinear (distance between A and B is 10 m), A stops moving "towards B with velocity 5 m/s …
Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time. To do this we work out the area of the nozzle and …
Addition of Velocities (Velocity Composition) in Special Relativity
May 20, 2024 · The “Addition of Velocities” formula (more correctly, the “Composition of Velocities” formula) in Special Relativity is a non-intuitive result that arises from a “hyperbolic …
Understanding Zero Velocity and Non-Zero Acceleration: Explained
Aug 1, 2009 · I heard it would be possible to have zero instantanous velocity & non zero acceleration (I know the opposite situation where there is velocity (constant), but zero …
Permeability of Metglas and Propagation Velocity
May 28, 2025 · The first is the velocity of wave propagation along the boundary between the material and air or space. That will be close to the speed of light, slowed down by the dielectric …
Question on Dirac's derivatives of the 4-velocity w.r.t. coordinates
6 days ago · As I said in #40, we can have a family of geodesics such that each has constant and a velocity . My original central geodesic is the same, , and the geodesics don't intersect. Since …
Velocity of Fluid flow due to gravity - Physics Forums
Apr 28, 2015 · Energy conservation is sufficient to get a good estimate - if some mass m leaves the pipe at a height h below the water surface of the tank, its kinetic energy is m*h*g, this …
How Do You Calculate Closing Velocities and Determine Their …
Aug 28, 2016 · If I'm not mistaken, the closing velocity is the velocity that the planes get closer to each other. And the closing speed is its magnitude, that is, the rate of change of the distance …
Minimum angular velocity of a point mass on a rotating rod
Jun 3, 2025 · Because the system has no friction, when the point mass falls, I think both angular momentum and energy are conserved. Further because the rod is massless, there cannot be …
Demystifying the Often Misunderstood Bernoulli’s Equation
Dec 3, 2018 · The goal of this post is to present Bernoulli's equation, its derivation based on energy conservation, and interpretations based on both momentum and energy conservation, …
