Define: (a)orbit (b) period of revolution (c) period of rotation
Answers
Answer:
a) In physics, an orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory.
b) astronomy the mean time taken for one body, such as a planet, to complete a revolution about another, such as the sun.
c) The rotation period of a celestial object (e.g., star, gas giant, planet, moon, asteroid) is the time that the object takes to complete a single revolution around its axis of rotation relative to the background stars.
Answer:
(A) An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them.
(B) The time period of a satellite of earth is 5 hours. If the separation between the earth and the satellite is increased to 4 times the previous value, the new time period will become.
(C) The rotation period of a celestial object (e.g., star, gas giant, planet, moon, asteroid) is the time that the object takes to complete a single revolution around its axis of rotation relative to the background stars.
