Unbalanced gyroscope precession.

The passive and active vibration isolation systems.

Collisions and scattering of particles.  Ballistic pendulum.

Bound oscillators. Energy is transferred from the first oscillator to the second one and back. As a result the amplitude of oscillation is periodically changed.  

Harmonic oscillation. An oscillating pendulum leaves a trace in the form of a sinusoid.

Satellite motion. Geo-stationary orbit. Kepler's law. Low Earth Orbit satellites. "Iridium".

Motion of a body in the presence of a gravitational field.

Black holes orbiting around each other in decaying orbits are merging with absorption of the gas and dust that surround them.

Motion of the body in the presence of the gravitational field.

Eratosthenes' measurement of the Earth's circumference.

Galileo's experiments with rolling balls down inclined planes.
