How does the length of a pendulum affect its period?

• The period is independent of the length

• The period decreases as the length increases

• The period increases as the length increases

• The period is proportional to the square of the length

Explain how energy is conserved in a simple harmonic oscillator.

• Energy is lost as heat

• Kinetic energy is converted to potential energy and vice versa

• Energy is created during oscillation

• Energy is only potential

What is the effect of damping on the amplitude of oscillation in a mechanical system?

• It increases the amplitude

• It decreases the amplitude

• It has no effect on the amplitude

• It causes the amplitude to fluctuate
