lirik lagu flipping physics - the energy song - by bo
[intro]
h~llo
my name is bo and this is “the energy song”
my project for ♫ flipping physics ♫
[chorus]
this is the energy song
sing it once and it won’t be long before you
know all three mechanical energies
know all three mechanical energies
[verse 1]
we’re about to learn, be prepared
kinetic energy is ‘1/2 m v squared’
remember … we’ve got the tools
to use work and energy in joules
[verse 2]
gravitational potential energy
the moon’s is lowest at perigee
the equation is ‘mgh’
‘m’ the mass, ‘g’ is 9.81
‘h’ is the vertical height
above the, gotta set the zero line
[verse 3]
pe of the elastic kind
‘1/2 k x squared’ is how it’s defined
‘k’s’ the spring constant, and don’t be a cheater
it’s got units of newtons per meter
know this in addition
‘x’ is the displacement from equilibrium position
[verse 4]
work is ‘f d cosine theta’
‘f’ the force for all your data
objects moves through displacement ‘d’
i think that we can all agree they’re only
two vectors in the work equation
theta’s the angle between the two of them
[bridge 1]
be careful, include
only ‘f’ ‘d’ magnitudes
[verse 5]
what happens if friction is not there?
flying through the vacuum you can breathe, called “no air”
all the energies are preserved
because mechanical energy is conserved
[bridge 2]
please, don’t disappoint
show your initial and your final points!
[chorus]
this is the energy song
sing it once and it won’t be long before you
know all three mechanical energies
know all three mechanical energies
[outro]
there you go
