Included Quiz Questions

When does a pendulum have a periodic motion similar to the periodic motion of an oscillating spring?

For small angle oscillations
For large angle oscillations
When the object on the end is very massive
When gravity is very small
When the pendulum is a pole instead of a string

If the length of a pendulum is doubled, by what factor does the frequency of small oscillations of the pendulum change?

1/√2
√2
2
1/2
It remains unchanged

If the mass on a pendulum is doubled, by what factor does the frequency of small oscillations of a pendulum change?

It remains unchanged
√2

1/2
1/√2

In the displacement of a spring away from equilibrium, spring potential energy was stored in the spring. What kind of potential energy is stored when a pendulum is displaced from equilibrium?

Gravitational potential energy of the mass
String potential energy of the pendulum's string
As the pendulum bar acts like a spring the potential energy is stored in the bar
Gravitational potential energy of the string of pendulum
The energy is stored in the stretching of the string or bar of the pendulum as it lifts the mass
