Conservation of energy. E= -mu/r + mcV
Conservation of E gives :
0=(d/dr + Del)m(-u/r + cV) = m(v^2/r - cv/r cos(x)) + m(cdv/dr + cDelxV -Del u/r).
The real part is zero:
mv^2/r - mcv/r cos(x) =0 so mv^2/r = mcv/r cos(x0 gives v/c= cos(x) =z the redshift and equilibrium.
The vector part is also zero and gives the orbit:
0 =dcV/dr + vc/r sin(x) T' + vc/r cos(x) R'
T' and R' are the Transverse and Radial unit vectors.
What else can I help you with?
Why do the planets orbit the sun What is the shape of those orbits?
Planets orbit the sun because gravity keeps them from escaping, and momentum keeps them moving forward. The orbits are elliptical, which is like an oval.
What keeps the planets in your solar system from floating away?
The force of the Sun's gravity keeps them in their orbits.
What part does gravity play in the paths of the planets?
Gravity is the force that keeps the planets in their orbits around the sun. It pulls the planets towards the sun, while their forward motion keeps them from falling into it. Gravity also influences the shape and stability of the planets' orbits.
What keeps us from floating off into the sky and keeps the planets in orbit around the sun?
Gravity is the force that keeps us grounded on Earth and planets in orbit around the sun. Gravity is a pulling force that attracts objects with mass towards each other. In the case of planets orbiting the sun, the gravitational force from the sun keeps them in their respective orbits.
What source keeps the planets from flying out of the solar system?
The force of gravity between the planets and the sun keeps them in orbit and prevents them from flying out of the solar system. The sun's gravitational pull keeps the planets in stable orbits around it.
What from the Sun keeps the planets in their orbits?
Gravity
Who keeps the planets in their orbits?
It isn't actually a who, but a what. That what is Gravity.
How are planets kept in there orbits?
The gravitational pull of the sun keeps the planets in orbits... Although some people think it is magnetism....
What keeps all of the planets in its orbit?
The gravitational force exerted by the Sun keeps all the planets in their orbits. This force balances the planets' tendency to move in a straight line and keeps them moving in elliptical orbits around the Sun.
What is the force that along with inertia keeps the planets in their orbits?
gravity
Why do the planets orbit the sun What is the shape of those orbits?
Planets orbit the sun because gravity keeps them from escaping, and momentum keeps them moving forward. The orbits are elliptical, which is like an oval.
How do planets stay on orbit?
The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
What keeps the planets in your solar system from floating away?
The force of the Sun's gravity keeps them in their orbits.
What part does gravity play in the paths of the planets?
Gravity is the force that keeps the planets in their orbits around the sun. It pulls the planets towards the sun, while their forward motion keeps them from falling into it. Gravity also influences the shape and stability of the planets' orbits.
What forces cause the planets to go around the sun and stay in their orbits?
The force of gravity between the planets and the sun is what keeps the planets in their orbits. Gravity pulls the planets towards the sun, but their forward velocity keeps them moving in a circular or elliptical path around it. This balance between gravity and velocity enables the planets to stay in their orbits around the sun.
What are the 2 forces not keeps the planets in their respective orbits?
Centripetal force and Gravity
What force keeps the planets moving forward in their orbits?
The force you seek is gravity.
