  • Vertical circular motion minimum speed proof - Physics Forums
    so the body reached the top let's take what happened so far, in reverse now the body has velocity of (rg)^0 5 to the other side, mg is still downward we KNOW the body will complete the half circle reversed motion, because we've just seen it complete it
  • Calculating Nozzle Flow Rate - Physics Forums
    for measuring velocity of water so we have to calculate velocity using head calculation or from stagnation pressure which we measure using a pitot tube Calculate Velocity from Head We can use Bernoulli's Equation to calculate velocity of a fluid from head Head is the distance from outlet to top of water V= 2gh V = Velocity m sec or feet per sec
  • Velocity of an Object Dropped from Height: Law Explained - Physics Forums
    This means that the velocity of the object will increase as it falls from a higher height, as more potential energy is being converted into kinetic energy However, it's important to note that this law assumes there is no air resistance or other external forces affecting the object's motion I hope this helps with your coursework
  • How to find the initial velocity given only angle and distance traveled
    An object is shot (from a cannon) at an angle of 33 degrees and landed 85 m away Calculate the magnitude of the initial velocity (Hint:Look at the x direction and solve for Vox) Homework Equations Other questions I must answer If you have time, help with these would be great, however I think if I can just find the initial velocity I should be
  • Relation Between Spring Constant and Angular Velocity - Physics Forums
    ω = angular velocity in rad s 2⋅π corresponds to one full rotation (2⋅π rad = 360°) If you want to know how many rotations are made in one second, you calculate ω (2⋅π) = f with f = frequency in s-1 Now you calculated how many rotations per second correspond to your ω
  • Converting velocity to pressure - Physics Forums
    Radiologists often use Doppler ultrasound to measure flow velocity change in a blood vessel with a stenosis- but I would like to make a conversion to a pressure differential Equation: P2-P1 = (V2^2 - V1^2) 2 (assuming frictionless system, blood density ~ 1 0 gm cm^3, and no change in height)
  • 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
  • Vector position, velocity, coordinates and speed - Physics Forums
    A particle initially located at the origin has an acceleration of vector a = 5 00j m s2 and an initial velocity of vector v i = 8 00i m s a)Find the vector position at any time t (where t is measured in seconds) (Use the following as necessary: t ) Find the vector velocity at any time t b)Find the coordinates of the particle at t = 2 00 s x
