Question

The motions that repeat themselves are called periodic
motions but for a simple harmonic motion, the force
must be proportional to the displacement and it is
directed towards the centre of motion.
a) Write an example for a periodic motion that is
not simple harmonic.
b) Write the expression for a period of oscillation of:
1) a loaded spring
ii) a simple pendulum
c) A particle executes a SHM of amplitude 'a'.
i) At what distance from the mean position is its
kinetic energy equal to its potential energy?
ii) At what points is its speed half the maximum
speed?​

Answer 1

Answer:

periodic motion is these motion are that respect themselves are called periodic motion for example -the bike has 60 of speed the tyre of bike was repeat and repeat
