- Vertical circular motion minimum speed proof - Physics Forums
hi, i've read in a lot of places that the minimum speed fora body to "finish" a vertical circle is (rg)^0 5, but I've never understood why they assume the
- Calculating Nozzle Flow Rate - Physics Forums
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 then multiply it by the velocity of the water coming from the nozzle to give us volume per unit of time
- Understanding Angular Velocity: W = 2pi (f) - Physics Forums
Can anyone explain to me how angular velocity (w) = 2pi(f) -->where f = frequency This is not a homework question involving numbers I'm reading a section on "the period of sinusoidal Nature of SHM" and I don't understand how they get this equation
- Calculating velocity of a particle if distances are constant
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 and B" stops moving "towards A with same speed as A" Indeed The equations will lead to the y coordinate (distance from C to the line AB) becoming imaginary
- Understanding Zero Velocity and Non-Zero Acceleration: Explained
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 acceleration)
- Demystifying the Often Misunderstood Bernoulli’s Equation
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, and its limitations
- How Is the Formula v=wr Derived in Vector Terms? - Physics Forums
The angular velocity ω is usually a scalar, rather than a vector quantity The magnitude of the radial velocity is given as v = ω r, where r is the magnitude of the radius vector
- Permeability of Metglas and Propagation Velocity
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 constant of the surface coating The second is the velocity of propagation into the material, perpendicular to the surface, which is much slower
