WAEC - Physics (2006 - No. 11)
which of the following statements about simple harmonic motion is correct? The
total mechanical energy is always conserved
linear acceleration is directed to any variable point
linear acceleration varies inversely with displacement
period of oscillation varies linearly as acceleration due to gravity
Explicação
In SHM, the total mechanical energy (the sum of potential and kinetic energy) remains constant, provided no damping or external forces are acting on the system.
