Use the equation below to find v if u=12,a=9, and t=4. v=u+at Equation of Motion: One of the equations of motion is v=u+at. It is used for finding the final velocity (v). To determine this velocity, we should know the acceleration (a), initial velocity ...
(physics) Any equation governing the behavior of a perturbation; often this will be a linear differential equation. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. Want to thank TFD for its existence?Tell a friend about us, ...
where P is the absolute pressure, ρ is the fluid density, v is the velocity of the fluid, h is the height above some reference point, and g is the acceleration due to gravity. If we follow a small volume of fluid along its path, various quantities in the sum may change, but the ...

The reality we can observe and measure is limited to rational numbers. Complex numbers are especially used in physics because of their beautiful properties, which translate into a powerful mathematical tool designed to solve many real-world problems. For example, the evaluation of a large class of...

In number theory we consider indeterminate equations, that is, equations in several unknowns for which we wish to find solutions that are integers or rational numbers (seeDIOPHANTINE EQUATIONS). For example, the integer solutions of the equation x2 + y2 = z2 are of the form x = m2 –n2...
How do you find centripetal acceleration given time and radius? First, one can use time to find the magnitude of the tangential velocity. The square of this result divided by the radius of the trajectory results in the value of the centripetal acceleration. What is centripetal acceleration write...
In subject area: Physics and Astronomy The Navier-Stokes Equations refer to a set of equations that combine the conservation of mass and momentum equations, including body force, pressure force, and viscous force, to calculate the unknowns of velocity components (u, v, w) and pressure (p) ...
Having surveyed the various forms of sound source in a qualitative manner, we now turn to mathematical representations of the physics of sound generation by linear mechanisms. The linearized wave equation was developed in Chapter 3 on the basis that the fluid element considered was not subject to...
