Derive the time period for simple pendulum..
Define oscillatory motion?
A girl is swinging in the sitting position. How will the time period of the swing change if she stands up?
Two particles execute SHM of same amplitude and frequency along same straight line.They pass one another when going in opposite directions.Each time their displacement is half of their amplitude.What is the phase difference between them?
How can we prove that motion of simple pendulum is a simple harmonic motion?
If two S.H.M.'s are represented by equations y1=10 sin[3pit+pi/4] and y2=5[sin (3pit)+31/2cos(3pit)],then find the ratio of their amplitudes & phase difference in b/w them.
why is a oscillatory motion always periodic but a periodic motion may not be oscillatory ?
Define linear and angular simple harmonic motion.
Also define the quantity in angular SHM which defines the same as force constant K in linear SHM.
Thk ya in advnce...:))

when the length of the simple pendulum tends toward infinity then what will be the time period of the simple pendulum?
WHAT IS PATH DIFFERENCE AND PHASE DIFFERENCE?
show that for a particle in SHM the average kinetic energy over a period of oscillation is equal to average potential energy over the same period. plz anyone help me fastt...got an exam tommorow...
