Question

Discuss the differences between simple pendulum and physical pendulum. Write the period equations and define all info associated with these periods.

Answer 1

Pendulams are type of object which enibits periodic oscilatory motion about a fixed point. Simple Pendulam : It consists of a hery point mass suspended by string which is weightless, in extensible and flexibles from a rigid support about which it executes periodic motion O Pinot Time Reriod = 27 stringy 1 0 Ł Axis length of pendetam мом from pinal gas aceleratim due to growity. Compound Pendulam : Also known as physical Pendulam, is extension of simple penderlam. It is a rigid body that is aber piusted about a point about which it executes periadic motion. (Oscillaton).
