The electronvolt 2.4.1 Flashcards
1
Q
what is the electronvolt
A
a unit which is commonly used to express very small energies
2
Q
what equation links potential difference, energy, charge
A
V = E / Q
V = potential difference (V)
E = energy (J)
Q = charge (C)
3
Q
what happens when a charged particle is accelerated through a potential difference
A
it gains kinetic energy
4
Q
what is the equation linking charge of electron, potential difference, mass, and velocity
A
eV = 0.5 mv^2
