# What is the symbol for velocity?

As is the case with many physical properties, the symbol for velocity is the word's first letter - 'v' ; however a Vector Notation (an arrow pointing right) should be placed over it so not to be confused with speed whose symbol is also a v.

### What is p equals mv?

That's the formula that defines momentum. For some reason unknown to me, the symbol commonly used for momentum is "p". Momentum = mass x velocity. That's the formula that defines momentum. For some reason unknown to me, the symbol commonly used for momentum is "p". Momentum = mass x velocity. That's the formula that defines momentum. For some reason unknown to me, the symbol commonly used for momentum is "p". Momentum = mass x velocity…

### What do youe mean by motion in physics?

Motion in physics means velocity or acceleration. v = change in displacement/ change in time = s/t a = change in velocity/ change in time = v/t NB in Science it is important to use the correct symbol including case. v is velocity but V is volume; a is acceleration but A is the symbol given to Mass Number; Ar is relative mass; t is time but T is temperature

### What are possible units of speed or velocity?

Answer #1: The most common unit of speed is kilometer per hour in the UK, and miles per our in the US. In the air and on water, it is measured in knots. ================================== Answer #2: (any unit of length)/(any unit of time) is a perfectly good unit of speed. Then, tell the direction of the length, and you have a velocity. Possible units of speed or velocity are miles per hour (symbol mi/h or…

### What is the symbol u in physics?

This has quite a few meanings, the most common is the starting velocity of an object. u is also somtimes used for kinetic energy U, written majuscule, is the symbol of the potential energy in U.S. the miniscule u can be the symbol of atomic mass unit, e.g 1 atomic mass unit (u) = 1.66053886 × 10-27 kilograms

### Why do all electro magnetic waves have the same velocity?

The velocity of the light wave is determined by the characteristics of the free space such as permeability and permittivity of free space. The expression of the velocity of the electromagnetic wave is given as 1/ ./mu0 epsilon 0 mu0 = 4 pi x 10 -7 H/m and epsilon 0 = 1/ 4pi*9*109 F/m Plugging these values we get the velocity as 3 x 108 m/s ./ is the square root symbol.

### What are the units of of measure for velocity and acceleration?

Acceleration is the rate of change of velocity. In other words, it is velocity divided by time. As velocity (in SI) is expressed in metres per second, acceleration must be measured in 'metres per second per second'. In fact, this is the correct way of 'saying' the unit of measurement for acceleration, NOT 'metre per second squared'. The symbol for metres per second per second is 'm/s/s' which, of course, is exactly the same as…

### What is wave velocity and particle velocity?

Wave velocity is a wave property, which may refer to: phase velocity, the velocity at which a wave phase propagates at a certain frequency pulse wave velocity, the velocity at which a pulse travels through a medium, usually applied to arteries as a measure of arterial stiffness group velocity, the propagation velocity for the envelope of wave groups and often of wave energy, different from the phase velocity for dispersive waves signal velocity or information…

### When throwing a ball straight up when is the velocity zero?

The velocity is zero when t=v0/g. This comes from velocity of the ball is v=v0-gt, where v0 is the velocity which the ball is thrown with, the initial velocity. The balls v velocity is the initial velocity v0 - the gravity velocity gt. when the real velocity is zero v= v0-gt=0. solving this for t gives when the velocity is zero.
