Question #d2662
1 Answer
In Simple harmonic Motion of an ideal particle instantaneous mechanical energy is given by the expression
At mean position
Kinetic energy
Similarly at extreme positions
The total mechanical energy remains constant instantaneously throughout the cycle. Therefore, total mechanical energy as it passes through a position that is 0.617 of the amplitude away from the equilibrium position is also equal to
To calculate actual value of total mechanical energy we need details of the Simple Harmonic Motion.
For example, if an ideal spring having spring constant
From equation (1) above
