What are the 2 forces that keep the planets in their orbit?
There are two forces that keep the planets in their orbits.
- Gravity. Gravity is the primary force that controls the orbit of the planets around the sun.
- Inertia.
- Gravity Working with Inertia.
- Velocity and Gravity.
What is the force that keeps planets orbiting the sun and moons orbiting planets?
Gravity is the force that keeps planets in orbit around the Sun. Gravity alone holds us to Earth’s surface. Planets have measurable properties, such as size, mass, density, and composition. A planet’s size and mass determines its gravitational pull.
Is orbit centrifugal force?
In the case of orbital motion, the outward pseudoforce that balances gravity is called the centrifugal force. An orbiting planet is in fact a freely falling body. Equation (42) is a special case (for circular orbits) of Kepler’s third law, which is discussed in the article celestial mechanics.
What are the 2 factors that keep the planets in orbit?
2 The two factors that combine to keep the planets in orbit are. gravity and orbital speed. orbital speed and mass. mass and inertia. gravity and inertia.
Which force keeps the planets from floating off into space?
Gravity Helps you not to float off into space with included mass. Adds weight/mass to pull the force down in space. While gravity is pulling the planets toward the Sun, and without inertia, all the planets would be pulled all the way to the Sun. Inertia Keeps you from slipping in space, with the friction in space.
What two factors keep the Earth and Moon in orbit?
Newton concluded that two factors—inertia and gravity—combine to keep Earth in orbit around the sun and the moon in orbit around Earth. Earth’s gravity keeps pulling the moon toward it, preventing the moon from moving in a straight line.
What force causes the planets to stay in orbit around the Sun?
Sun has energy density or density. Energy density causes space-time to bend and this is called gravity. It is centripetal gravitational force that causes planets to revolve around the sun in orbits.
