An orbit is made possible by an equilibrium, or balance, of forces. Typically, this involves two forces: one of gravitational attraction between the objects and another caused by centripetal acceleration. At a given radius of orbit, a velocity can be found such that these two forces are equal, keeping the object in orbit.

What two motion form an orbit?
An orbit is formed when an object is moving in a curved path around another object due to the gravitational pull between them. The two motions involved in an orbit are the object's forward motion (tangential velocity) and the pull of gravity keeping it in a curved path (centripetal force).
What two motions combine in order to cause orbiting?
Inertia, the tendency of an object to keep moving in a straight line, combines with gravity, the force that pulls objects together, to cause orbiting. The inertia of an object causes it to keep moving forward, while gravity continuously pulls it towards the center of the orbit, creating a balance that results in a circular or elliptical path around another body.
What 2 things keep something in orbit around the earth?
The two things that keep something in orbit around Earth are the object's velocity, which must be high enough to counteract gravity and maintain a stable path, and the gravitational pull of Earth, which pulls the object towards the planet's center. Both factors work together to keep the object moving in a circular or elliptical path around Earth.
What are two criteria needed for a space object to be considered a planet?
Two criteria for a space object to be considered a planet are: (1) it must orbit the Sun, and (2) it must have enough mass for its gravity to pull it into a roughly spherical shape. Additionally, it must have cleared its orbit of other debris.
What is the meaning of the word orbit?
Orbit has the following two meanings:the curved path of a celestial object or spacecraft around a star, planet, or moon. (noun)move in orbit around a star, planet or moon. (verb)

What two types of motions keep a satallite in orbit around earth?
A tangential velocity vector relative to the orbit itself, and acceleration towards the center of the planet due to gravity.
What two motions combine in order to cause orbiting?
Inertia, the tendency of an object to keep moving in a straight line, combines with gravity, the force that pulls objects together, to cause orbiting. The inertia of an object causes it to keep moving forward, while gravity continuously pulls it towards the center of the orbit, creating a balance that results in a circular or elliptical path around another body.
What keeps objects in orbit in our solar system?
Gravity combined with the object's "sideways" (tangential to its orbit) motion. The Sun "wants" to pull the object towards it and the object "wants" to fly of into space. When these two things are balanced the object is in a stable orbit.
What two motions act upon a satellite to keep it in motion?
Gravity and inertia.
What 2 things keep something in orbit around the earth?
The two things that keep something in orbit around Earth are the object's velocity, which must be high enough to counteract gravity and maintain a stable path, and the gravitational pull of Earth, which pulls the object towards the planet's center. Both factors work together to keep the object moving in a circular or elliptical path around Earth.
What two motions combined make the moon orbit Earth?
Velocity and gravity (movement around the Earth and the gravity of the Earth pulling on it).
What are the two factors affect the gravitational attraction between two object?
gravity and its orbit
What are the earths two principal motions?
The two principal motions of Earth are rotation and revolution. Rotation refers to the spinning of Earth on its axis, which causes day and night. Revolution refers to Earth's orbit around the sun, which takes approximately 365.25 days to complete.
What two things keep the planets in their orbit?
gravity&inertia
What are two major motions of earth as it travels through space?
The two major motions of Earth as it travels through space are rotation, which is its spinning on its axis causing day and night, and revolution, which is its orbit around the Sun causing the changing of seasons.
Why does the speed of an object increase as it gets closer to the object its orbiting?
As an object gets closer to the object it's orbiting, the gravitational pull between the two objects increases. This causes the object in orbit to accelerate, increasing its speed to balance the gravitational force and maintain its orbit.
