hiiiiyaa
can anyone plz tell me wut the following formulas and symbols are for? we so have not been taught this

E = F/q

P = VI.....umm does this one stand for power?

Energy = VIt

ohhh and this one plz (i jus forgot wut this one is thats all)
Vx=Ux (pretend the v's and u's are lil and the x's are subscript)
tank U!!!

E = F/q

This formula describes the forces acting on a charged particle, while in an electric field.

E = Electric field strength (V/m or N/C)
F = Force (N)
q = Charge (C)

P = VI.

This formula is for determining the power being produced or consumed by an element (e.g. resistance) in an electric circuit.

P = Electrical power (W)
V = Voltage (V)
I = Current (A)

Energy = VIt

This formula tells you how much electrical energy has been produced or consumed by a circuit element. It similar to the above, it just makes use of the fact that energy = power*time

V = voltage(V)
I = current (A)
t = time (s)

Vx=Ux

This could mean a number of things, but I'm guessing it's about projectile motion:

Ux = initial horizontal velocity
Vx = final horizontal velocity

All it means is that the velocity in the horizontal direction is constant (i.e. there's no horizontal force in projectile motion).
