Question

Derive an expression for energy of a particle executing simple harmonic motion. If the

displacement of two particle executing simple harmonic motion are represented by equations y1 =

4 sin (10t+/) and y2=5 cos10t, then what is the phase different between the velocities of these

particle​

Answer 1

Answer:

An acceleration can cause speed to increase, decrease, and even stay the same! Acceleration tells you the rate at which the velocity is changing. ... The acceleration can change the magnitude and/or the direction of the velocity. Speed is only the magnitude of the velocity.
