What keeps planets in elliptical orbits?
Planets are kept in elliptical orbits due to the gravitational force acting between the planet and the sun. This force causes the planet to move in a curved path, resulting in an elliptical orbit. The balance between the planet's inertia and the gravitational force determines the shape of the orbit.
What 2 forces combine to keep a planet in orbit?
There are two factors; the tangential velocity, and the gravitational force. The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force is constantly attracting the planets in, against this tangential velocity. If the planets were to slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.
What forces act to hold a planet in orbit around the sun?
The gravitational force between the planet and the sun is what holds the planet in orbit around the sun. This force keeps the planet moving in a curved path around the sun, in balance with the planet's inertia.
What would happen to an object in orbit around planets if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.
What would happen to an object in orbit around a planet if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.
What were the two factors Isaac Newton concluded that combined to keep the planets in orbit?
Isaac Newton concluded that the force of gravity and the forward motion of the planets combined to keep them in orbit around the Sun. The force of gravity pulls the planets towards the Sun, while the forward motion of the planets creates the centrifugal force that counteracts gravity, leading to stable orbits.

Newton learned that the orbits of planets are the result of what two forces?
Newton learned that the orbits of planets are the result of the gravitational force between the planet and the Sun, which causes the planet to move in an elliptical orbit, and the planet's inertia, which causes it to continue moving in a straight line.
What forces act to hold a planet in orbit around the sun?
The gravitational force between the planet and the sun is what holds the planet in orbit around the sun. This force keeps the planet moving in a curved path around the sun, in balance with the planet's inertia.
What would happen to an object in orbit around planets if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.

The object would crash into the planet.
What makes planets revolve around the sun?
Planets revolve around the sun due to the gravitational force exerted by the sun. This force keeps the planets in orbit as they move through space, following elliptical paths. The balance between the planet's inertia and the sun's gravitational pull determines the planet's orbit around the sun.
How do gravity and inertia keep the planet in orbit around the sun?
inertia keeps the planets moving and spinning , and gravity is a force that attracts all objects toward each other.
What are two forces that keep the planets revolving around the sun?
The force of gravity pulls the planet towards the Sun and this is balanced by the planet's "centrifugal force" away from the Sun. (Centrifugal force is called a "fictitious force" in physics. It's a mathematical way of representing the planet's tendency to move in a straight line path. Some people prefer to talk about the planet's "inertia" rather than centrifugal force.)
What force keeps the planets together?
Gravity and inertia.
What two factors act together to keep the planets in orbit around the sun?
definetly Gravity and Inertia
