A concentrated mass resulting from gravitational collapse near which gravity is so strong not even light can escape is called a ].
The ratio of the output energy for a machine to the total input energy is called the of the machine.
“For any pair of objects, each body attracts the other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers of mass.” This is a statement of .
is the rate at which work is done or energy is transformed: work/time.
is the number of rotations per unit time.
The product of the force and the lever arm on a body which imparts a rotational acceleration on the object is called .

Explain how Newton’s Law of Universal Gravitation can be used to explain how the planets orbit the Sun (or satellites orbit the Earth) and use the law to derive Kepler’s third law for planets orbiting their sun in a circular orbit. For the 6 planets closest to the sun find, from the internet or elsewhere, the mean distance from the sun (in astronomical units) and their orbital period (in years). Use this information to plot, using a software package, an...

Black Hole has such a huge gravity, impacting space and matter in its vicinity the way that velocity reaches infinity, thus the time is close to zero, why or why not? include a short description of the Black Hole (how it forms, its characteristics after it forms and the definition of the Event Horizon. Perhaps you can also come up with a live example, which would help to explain the processes happening around the black hole.
