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 motions combine in order to cause orbiting?
I'm pretty sure that gravity and inertia cause something to orbit around another object.
What two forces work together to keep the planets in orbit around the sun?
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
What two things keep the planets in orbit?
gravity and string
What two factors keep a planet in orbit around the sun?
Gravity and inertia
Which two forces of a result is the orbit of the planet?
Gravity, which pulls an object inward, and inertia, which resists gravity. They combine to form a more-or-less circular orbit.
What two motions combine in order to cause orbiting?
I'm pretty sure that gravity and inertia cause something to orbit around another object.
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 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 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 motions act upon a satellite to keep it in motion?
Gravity and inertia.
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 two forces work together to keep the planets in orbit around the sun?
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
What two things keep the planets in orbit?
gravity and string
What two things keep the planets in their orbit?
gravity&inertia
What two motions does the earth make in the space?
The Earth is in orbit round the Sun, but also the Sun is moving round the centre of our galaxy, and of course we follow along.
How does the unbalanced force of gravity affect the horizontal and vertical velocity of an object in projectile motions?
well...projectile motion is made of two different motions, or movements- horizontal movement and vertical movement so... i guess that it
