You need to
learn the equations:

·
Applied
force = spring constant x extension

·
Elastic
Potential Energy = ˝ x spring constant x (extension)^{2}

·
Wave speed
(m/s) =
frequency (Hz) X
wavelength (m)

·
Frequency =
1/time period

·
Efficiency =
useful energy output / total energy input

·
Power
(W) =
energy used (J) /
time taken (s)

·
Heat Energy Supplied = mass X specific heat capacity X temperature
rise

·
Heat transferred (J) = mass
of substance (kg) x specific latent heat (J/kg
