Yes
None do. If the forces on a planet were balanced, then it would take off in a straight line at constant speed, not remain in orbit. The only force acting on a planet is the gravitational one, that attracts the planet toward the sun. Fortunately, that's the only force required to keep the planet in orbit.
Yes, planets generally have stronger gravity than moons because planets are larger and more massive. Gravity depends on an object's mass and distance, so the greater mass of a planet typically results in stronger gravitational pull compared to moons.
Planets and satellites orbit the sun due to the gravitational pull of the sun. This gravitational force keeps them in their respective orbits as they move through space. The balance between the inertia of the planets/satellites and the gravitational force of the sun results in stable orbits.
Planets are round due to gravity pulling material towards their center, which results in a spherical shape. This is known as hydrostatic equilibrium, where gravity balances the internal pressure caused by the material pushing outwards. Over time, this gravitational force molds planets into the most energy-efficient shape, which is a sphere.
Gravity is the force that keeps planets in orbit around the sun. It pulls the planets towards the sun, causing them to move in a curved path rather than a straight line. Gravity also affects the speed at which planets orbit the sun, with closer planets moving faster than those further away.
The movement of planets within the solar system is primarily due to gravitational forces exerted by the sun. The sun's gravity keeps the planets in orbit around it, while their own momentum and inertia cause them to move in their respective paths. This dynamic balance of forces results in the planets' continuous motion.
the planets are situated at the orbit shell of the sun, ie they are continuously in a falling motion....however, due to the spherical shape of the sun...their falling motion never results in a collision....if the gravity of the sun was even fractionally lesser....the planets closest to the sun would change from an elliptical path to following a spiral one until they ultimately collapse in the sun....hope i helped
Inertia. Newton's fist law states that an object that is moving will keep moving until somethings slows it down. Since there is virtually no friction in space, nothing causes the planets to slow down, so they continue to orbit.
It would be Bad!
Tides are the result of lunar (and solar) gravity.
Gravity and Inertia. Gravity pulls the planets toward the sun, but inertia pulls it away. They keep it evenly balanced. angular velocity is balanced (mostly) by gravity. Answer2: The planets stay in orbit because the centripetal force of gravity vp/r is balanced by the centrifugal force cp/r cos(P). the centrifugal force is the divergence of the "Dark Energy" cmV =cP. The real gravity energy is w = -mGM/r + cmV = -vp + cP where -vp is the potential scalar energy and cP is the vector energy, the so-called "Dark Energy". The vector energy is the force balancing the gravitational centripetal force. vp/r = cp/r cos(P) thus v/c = cos(P). This is the red shift and explains what the red shift is. The Dark Energy is the vector energy associated with the Momentum mV. Dark Energy creates the orbit from : 0 = cdP/dr + muR/r3..
