Question: What force determines the motions of planets and other objects in the solar system gizmo?

The Sun’s gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. Even spacecraft are in motion through the solar system, either in orbit around the Earth or Moon, or traveling to further worlds, because of gravitational forces.

What force determines the motion of planets in the solar system?

The sun’s gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun’s gravitational pull, all the planets in our solar system orbit around it.

What force determines the motions of planets and other objects in the solar system quizlet?

The gravity of the sun causes the Earth and other planets to orbit around it. The farther away two objects are from each other, the weaker the force of gravity between them.

What force keeps the planets from flying out of the solar system gizmo?

The sun was the balloon. The closer to the sun the shorter the orbit. By holding the spring we created a form gravity so the planets cannot fly out of their orbits.

Vocabulary Sheet

The Sun, which scientists call Sol, is the largest object in our solar system. If it were the size of a basketball, all the other planets would comfortably fit inside a ping-pong ball! Heat is produced in its core when hydrogen is fused into helium.

What causes the motion of the planets?

The force of gravity causes the moving planets to travel in roughly circular orbits around the sun. They have been circling the sun for billions of years because other forces have been too weak to change the orbits in any significant way.

How does the force of gravity determine the motion of planets and satellites?

The force of gravity acts upon a high speed satellite to deviate its trajectory from a straight-line inertial path. Indeed, a satellite is accelerating towards the Earth due to the force of gravity. Finally, a satellite does fall towards the Earth; only it never falls into the Earth.
