No it is not because Earth is not oscillating freely, but under the influence of the Sun's gravity field.

Google Earth is a virtual globe, map and geographic information program that was originally called EarthViewer 3D. It maps the Earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. It is available under three different licenses: Google Earth, a free version with limited functionality; Google Earth Plus, which included additional features; and Google Earth Pro ($400 per year), which is intended for commercial use. You can download the free version from the link mentioned in the related links.
Because it can and it's free.
No, Google Earth Pro is the paid professional version that costs $399 per year.It does have a free 7-day trial period to use and evaluate after which you need to convert trial license into full license.Note that Pro and free version both use the same high-resolution imagery.*UPDATE* as of Jan 30, 2015 Google made Google Earth Pro available for free. Login with your email address and the license key GEPFREE and that's it.
Motion of pendulum.
No, a pendulum of a clock is an example of a free oscillation. Forced oscillation occurs when an external force drives an object to oscillate at a frequency different from its natural frequency, whereas a pendulum naturally oscillates at its own frequency without an external force.
If a circuit is unstable and oscillates then the term free oscillation can be applied.
In absence of any external force, the body would oscillate indefinitely with a constant amplitude a, then it is called free oscillation. When a body, being acted by an external periodic force ,oscillates with the frequency of the force, then the oscillation of the body is called forced oscillation.
It is a side to side motion like a pendulum in a clock
A Foucault pendulum is a pendulum with a large length which is free to oscillate in any vertical plane. At the equator, the plane of oscillation remains fixed relative to the earth. Elsewhere, the plane of oscillation rotates, at a speed that is related to the latitude of the location. In Paris, where Foucault's pendulum is located, the plane of the pendulum's oscillation moves at approx 11 degrees per hour. This movement can be used to tell the time.
The main types of oscillation of a sprung weight in a vehicle are natural frequency oscillation, pitch oscillation, and bounce oscillation. Natural frequency oscillation is the frequency at which the sprung weight naturally oscillates when disturbed, pitch oscillation involves tilting forward and backward, and bounce oscillation involves vertical up and down movement.
The frequency of a free falling object is determined by the rate at which it falls due to gravity. This rate is typically constant (9.8 m/s^2 on Earth) and results in a consistent frequency of oscillation for the object as it free falls.
Oscillations (vibrations) are damped when they are changed by some action. For example, touching an oscillating (vibrating) tuning fork with your finger is said to be damping it. The oscillation (number of Hertz) of an electrical oscillator, such as a TV tuner, is changed by varying the settings of the tuner.
A wave is a back and fro motion of particles due to vibration or oscillation, example: The sound wave which is due to the vibration of the vocal cords.
An example of damp oscillation is when a car's suspension system absorbs the energy from bumps on the road, causing the car to bounce up and down in a controlled manner before coming to rest. The damping effect reduces the oscillations over time, preventing the car from continually bouncing.
Wouldn't that depend on what's doing the oscillating ? If it's a stone on the end of a rubber band, or a pendulum, or anything else like that where the period depends on the weight of something, then of course it's going to be different, because the weight of the weight is different. But if it's an oscillation of voltage and current in an electronic circuit, then weight/gravity has nothing to do with the frequency. The frequency of radio transmissions from astronauts in flight, as well as the frequency of their voices for that matter, is the same whether they're on Earth, on the moon, or weightless in orbit somewhere.
