- 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
- Finding Velocity given x and y velocities - Physics Forums
1 How do you find the velocity of an object if you are given the x and y components of the velocity? 2 Not sure! 3 It makes the most sense to use the Pythagorean Theorem to find the magnitude then trig to find the angle, but I've got a classmate telling me you simply add together the x and y components Which is 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
- Understanding Zero Velocity and Non-Zero Acceleration: Explained
The problem here is that you have a fundamental misunderstanding of what acceleration means in relation to velocity Consider a curve of velocity vs time At some time, t, the instantaneous velocity is zero The acceleration is the slope of the velocity curve at time t You are confusing a value on a curve with its slope
- Permeability of Metglas and Propagation Velocity - Physics Forums
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
- 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
- Velocity of Fluid flow due to gravity - Physics Forums
For our purposes, in this project we are assuming the height in the tank is constant, as you said This will ensure a constant pressure at the bottom of the tank, in theory keeping the flow of water constant I originally thought I could use the kinematic equations of physics to solve for the velocity after free falling a certain distance "h"
- Solving for distance using only initial velocity and coefficient of . . .
At the early point (probably around chapter 4) of an "elementary physics" textbook, a student encounters problems where, given an initial velocity and coefficient of friction, the student is expected to provide the resulting final displacement This is a stage of the textbook where kinetic energy equations and "work" equations have not yet been
