One scientist wants to put an 100kg experimental package in orbit around the Earth. The cost of deployment depends on the amount of more extra energy it takes to get it into the required position i.e. how much more energy is used than just sending the rocket up there.
a) Verify the amount of work that must be completed to get the package to 1 000km above the Earth’s surface.
b) Verify the amount of extra work required to put the package into a circular orbit at this height.
Obtain Relativistic expression for the kinetic energy of the particle. Derive mass energy relation. Show that total energy E and momentum P are related, where m is rest mass and
When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 7.5 km/s and the secondary, or S, wave
Principle of uniqueness of freefall: The idea inside general relativity that the worldline of a freefalling body is independent of its, structure, composition or state. This p
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
