An anharmonic solution to the equation of motion for the simple pendulum In the small-angle regime the formula becomes equivalent to the result for the period of the linear pendulum. The present derivation of an anharmonic ... K Johannessen - 《European Journal of Physics》 被引量: 17发表:...
We extracted 9 orientation-invariant heuristic features using the formula [26] to address the orientational dependency problem. Since the participants had the freedom to place the smartphones in the pre-determined position in any orientation, we experienced different ranges and patterns in sensor values...
Simple harmonic motion, in physics, repetitive movement back and forth through an equilibrium, or central, position, so that the maximum displacement on one side of this position is equal to the maximum displacement on the other side. The time interval f
