An object undergoing simple harmonic motion will always have varying acceleration. That means for each unit of time passing by, different distances will be covered within the bounded amplitude. As an example suppose T= 10s. Therefore, f = 1/T = 0.1 Hz(1/10th of a wavelength). This in a way would...
Hey guys.. can somebody please comment on my idea and tell me if i am right or wrong?? I am sort of confused myself... and there are a lot of different answers i am finding everywhere that has confused my head too !
Hey R Power, why should the foot 'accelerate' in the forward direction. I feel, while walking, the foot is stationary relative to the ground, while only the torso and leg move forward !
Your bullet-gun anology has a good point though.. as i too feel that the questioner has made all the forces...
You know what i think guys ! Just guessing--
lets say the person is walking from a viewer's left to his right... then, the contact force b/w foot and ground will have two components: one down right inside to the ground(which is canceled by the Earth's normal reaction); and the other.. to the...
