Mechanical Energy
Potential energy
Gravitational Potential Energy
:
GPE = mgh
height [m]
gravitational potential energy [j]
gravitational acceleration [m/s^2] = 9.81 m/s^2
m = mass [kg]
Elastic Potential Energy
EPE = 1/2 kx^2
Spring Constant
For n springs in series: 1/(K total) = 1/K1 + 1/K2 + 1/K3 + ...+ 1/Kn
For n springs in parallel: K total = K1 + K2 + K3 + ... + Kn
k = spring constant [N/m]
x = displacement of the spring from neutral position [m]
EPE = elastic potential energy [J]
Spring force
Spring Force (Fsp) = - kx
x = displacement from equilibrium [m]
k = the spring constant [N/m]
Kinetic Energy
KE = 1/2 mv^2
m = mass [kg]
v = velocity [m/s]
KE = kinetic energy [J]
Principal of conservation of mechanical energy
Energy cannot be created or destroyed
KE1 + PE1 = KE2 + PE2
