... A mass on a spring oscillates back & forth with simple harmonic motion of amplitude A. A plot of displacement (x) versus time (t) is shown below. At what points during its oscillation is the speed of the block biggest? 1. When x = +A or -A (i.e. maximum displacement) 2. When x = 0 (i.e. zero displac ...

... The force on the mass is maximum at point E , since the force Fspring = –kx is maximum magnitude there. The acceleration is maximum at point E (Newton's second law says Fnet = m a, so the acceleration is max when Fnet is max.) The elastic potential energy (PEelas = ½ kx2) is maximum at E (where x is ...
