In classical mechanics, U is often used to represent potential energy. In particular, it is used as a symbol for gravitational potential energy and elastic potential energy. In electrodynamics, U is used to represent electrical potential energy. In thermodynamics, U is often used as a symbol for internal energy.
What do you represent in the physics of electricity?
U is the energy measured in joules. V is the energy per coulomb of charge, measured in volts. They’re similar, but let’s say you were asked about the potential energy of an electron.
What is the weird U in physics?
Symbols of physical quantities and their international units
| symbol | size | unit |
|---|---|---|
| U , U E | potential energy, electric potential energy | joule |
| V, V < sub>E | Voltage, potential, electric potential | Volt |
| ℰ | electromotive force, emf | volts |
| C | capacitance | farads |
What does R mean in electricity physics?
R = resistance. R = molar gas constant. R = reaction force.
What are U and V in physics?
The equations of motion relate to the following five variables: u Initial velocity. v final velocity. an acceleration.
What does µ mean?
Micro (Greek letter μ or ancient symbol micro μ) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth). The prefix, confirmed in 1960, comes from the Greek μικρός (mikrós), meaning small. The prefix symbol comes from the Greek letter μ (mu).
What does T mean in physics?
a = acceleration ∆v = change in velocity ∆ t = elapsed time The definition of acceleration. … ∆x = displacement vf = terminal velocity ∆t = elapsed time a = acceleration Use this formula if you don’t have vi.
