Schrödinger's equations, I believe
quantum mechanics.
Quantum Electrodynamics theory
Yes since the molecules all come closer together. This means that the sphere would have more difficult time traveling downward because the particles are so packed
A group of several ships traveling together is called a convoy.
Temperature IS the (average) speed of movement of the particles (molecules) that make up an object. The more heat you add to an object, the faster the molecules move (vibrate). There are devices (thermometers) that indirectly measure this speed, and thus report the temperature.
Longitudinal waves consist particles in a medium (ex of a medium= air) vibrate back and forth in a parallel direction to the direction of the wave is traveling. Example of a longitudinal wave are sound waves. Boom! Opposite of longitudinal waves would be a transverse wave where instead of particles moving in a parallel direction, transverse waves vibrate in a medium, side by side perpendicular to the direction the wave travels to. Example of a transverse wave is a light wave. Hope this helped =]
It doesn't have mass or take up space. <><><><><> Light is energy, and energy is matter, according to Einstein. Besides, it has been proved that light is affected by Gravity and, in order to do that, it has to have mass. Look again at Einstein and others, such as Lorentz... The photon has no mass, or does it? True, it seems to have no mass, but that is at rest state. Multiply that by infinity to account for mass increase and time dilation due to traveling at the speed of light, and what do you get? Something that looks like a particle, having mass, traveling at the speed of light.
Every living creature discovers motion. Isaac Newton was the one who put in into mathematical physical equations that could be used for things like traveling to other planets.

Cosmic radiation are highly energetic particles, traveling at very high velocities. When they collide with atoms, they ionize them, practically breaking them apart. When that happens on critical molecules such as D.N.A, it's bad for you.
No. Velocity includes a directional component. If the two were of the same mass and collided head-on, their velocities (being in the reverse directions) would cancel out.
Yes. If they are traveling in the same direction and at the same speed, then they have the same velocity.
photons
When they travel in different directions, obviously, since velocity is made up of a speed and a direction.
Generally increase with depth, occasionally making abrupt jumps termed seismic-velocity discontinuities.
When the Earth is traveling, everything on the Earth is traveling with it, in the same frame of reference. For example, when you are in a car or an airplane and you flip a coin in the air, the coin doesn't shoot backwards. Or, notice that when you jump upwards that the Earth didn't move from under you when you jumped.
No the two buses do not have equal velocities because VELOCITY is the SPEED in a given DIRECTION. One would have a velocity of +30m/s because it is traveling in one direction, and the other would have a velocity of -30m/s because it is traveling in the opposite direction.
take all the particles out of the air, effectively making it a vacuum
