What are the two main forms of energy in SHM?
Kinetic energy (K = ½mv²) and potential energy (U = ½kx²)
Write the total mechanical energy in SHM.
E=K+U=1/2mv2+1/2kx2
When is the energy all potential?
At the maximum displacement (x = ±A).
When is the energy all kinetic?
At the equilibrium position (x = 0).
What is the total mechanical energy in terms of amplitude?
E=1/2kA2
Is total mechanical energy constant?
Yes, it is conserved in a frictionless system.
What is the velocity as a function of position in SHM?
v= ±ω sqrt(A2−x2)
What is the difference between total mechanical energy and total energy?
Total mechanical energy = kinetic + potential (in ideal systems).
Total energy = includes all forms (mechanical, heat, sound, etc.).
