$Ek =$ $0.5*$ $m*$ $v^2$
Kinetic Energy = 0.5 x mass x (speed)^2
$Ee =$ $0.5*$ $k*$ $e^2$
Elastic Potential Energy = 0.5 x spring constant x (extension)^2
$Ep =$ $m*$ $g*$ $h$
Gravitational Potential Energy = mass x gravitational field strength x height
$∆E =$ $m*$ $c*$ $∆ θ$
change in thermal energy = mass x specific heat capacity x temperature change
$P=$ $E/t$
power = energy transferred / time
$P=$ $W/t$
Power = work done / time
efficiency = useful output energy / total input energy transfer
efficiency = useful power output / total power input
$Q=$ $I*$ $t$
charge flow = current x time
$V=$ $I*$ $R$
Potential difference = current x resistance
$P=$ $V*$ $I$
Power = potential difference x current
$P=$ $I^2*$ $R$
power = (current)^2 x resistance
$E=$ $P*$ $t$
energy transferred = power * time
$E=$ $Q*$ $V$
Energy transferred = charge flow * potential difference
$Vp *$ $Ip =$ $Vs *$ $Is$
potential difference across primary coil x current in primary coil = potential different across second coil x current in secondary coil
$p =$ $m/V$
density = mass / volume
$E =$ $m*$ $L$
thermal energy change of state = mass x specific latent heat
$W=$ $m*$ $g$
weight = mass x gravitational field strength
$W =$ $F*$ $s$
Work done = force x distance (along the line of action of the force)
$F=$ $K*$ $e$
force = spring constant x extension
$s=$ $v*$ $t$
distance travelled = speed x time
$a =$ $\Delta v /t$
acceleration = change in velocity / time taken
$v^2-u^2=$ $2*$ $a*$ $s$
(final velocity)^2 - (initial velocity)^2 = 2 x acceleration x distance
$F=$ $m*$ $a$
resultant force = mass x acceleration
$p=$ $m*$ $v$
momentum = mass x velocity
$T=$ $1/f$
period = 1 / frequency
$v =$ $f*$ $\lambda$
wave speed = frequency x wavelength
$F=$ $B*$ $I*$ $l$
force on a conductor (at right angles to a magnetic field) carrying a current = magnetic flux density x current x length
