Mechanical Energy - Coggle Diagram
Mechanical Energy
Gravitational Potential Energy
Formula
-
GPE = mgh
where
m = mass [kg]
g = gravitational acceleration [m/s2] = 9.81 m/s2
h = height [m]
GPE = gravitational potential energy [J]
Kinetic Energy
Formula
KE = ½ mv2
Where
m = mass [kg]
v = velocity [m/s]
KE = kinetic energy [J]
Principle of Conservation of Mechanical Energy
Formula: Mechanical Energy = Potential Engery + Kinetic Energy
KE1 + PE1 = KE2 + PE2
Elastic Potential Energy
Formula
-
EPE = ½ kx2
where
k = spring constant [N/m]
x = displacement of the spring from neutral position [m]
EPE = elastic potential energy [J]
SI Unit
Joules (J)
