Question

Relationship between time period for oscillation pendulum and its energy loss

Answer 1

Answer:

Explanation:

As the pendulum swings back and forth, there is a constant exchange between kinetic energy and gravitational potential energy.

Your investigations should have found that mass does not affect the period of a pendulum. One reason to explain this is using conservation of energy.

If we examine the equations for conservation of energy in a pendulum system we find that mass cancels out of the equations.

KEi + PEi= KEf+PEf

[½mv2 + mgL(1-COSq) ]i = [½mv2 + mgL(1-COSq) ]f

There is a direct relationship between the angle θ and the velocity. Because of this, the mass does not affect the behavior of the pendulum and does not alter the period of the pendulum.
