What happens when the planets stop moving?
If the planets were to suddenly stop moving, they would no longer orbit the sun due to the lack of gravitational pull. Without their orbital motion, the planets would likely drift off into space in a straight line until they either collided with something or were gravitationally attracted to another object. This scenario is purely hypothetical as the laws of physics dictate that the planets will continue to orbit the sun.
If the force of gravity suddenly stopped acting on the planets they would do what?
If the force of gravity suddenly stopped acting on the planets, they would continue moving in a straight line at a constant speed, following Newton's first law of motion. Without the force of gravity to pull them towards the Sun, the planets would travel in a tangential direction away from their current orbital paths.
What are moving stars?
Planets; from 'Planetes,' or 'Wanderers.'
What are two things that work together keeping planets in their orbits around the sun?
Gravity and the laws of motion, specifically Newton's laws of motion, work together to keep planets in their orbits around the sun. Gravity from the sun pulls the planets towards it, while the inertia of the planets moving in a straight line causes them to travel in an elliptical orbit around the sun.
How does the sun stay in orbit?
The Sun stays in orbit because of gravity. This is also why all the planets stay in orbit too. Gravity pulls the planets towards the Sun. Without gravity, the planets would be wandering all over the universe.
Newton's 1st law of motion states that a moving object will go in a straight line unless an outside force changes this motion What outside force prevents the planets from moving in a straight line in?
It's not that there is some force keeping the planets from falling into the sun; the sun's gravity prevents the planets from travelling in a straight line out of the solar system. If you throw a ball in a straight line then it keeps going, but if you throw a ball on a rope tied to a pole then the rope pulls the ball toward the pole and keeps the ball moving in a circle.
What will happen to an object moving at a constant speed if no outside forces act on it?
It's not necessary to specify that the object is moving at a constant speed. Any object with no outside forces acting on it does that. It also continues moving in a straight line.
Which law of motion states an object moving in a straight line will continue moving in a straight line at the same speed unless acted on by an outside?

What prevents a moving bike from coasting forever in a straight line?
Friction. Air friction, road friction and mechanical friction.
Why don't planets travel in straight line?
Inertia is the tendency of objects to keep moving in a straight line. They "want" to go in a straight line, so to speak. However that is changed when a force acts on them. In the case of planets, that force is the gravitational force between the planet and the Sun.So that's why planets orbit the Sun instead of traveling in a straight line.
What force keeps the ball moving in a circle?
The force that keeps a ball moving in a circle is called centripetal force. This force acts towards the center of the circle and prevents the ball from moving in a straight line.
What prevents the diver from moving in a straight line once she jumps from the platform?
If there is any horizontal component to the diver's velocity, then that will cause a parabolic path instead of a straight line fall due to gravity.

What is the force that keeps the planets from moving close to the sun?
No force is needed, which is lucky because there isn't any. A planet's speed in the direction of its orbit prevents it from falling in closer.

Why does gravity cause the planets to revolve around the sun instead of falling into it?
Actually, gravity is the force that would cause planets to fall into the sun. It is centripetal force that keeps the planets revolving and not falling. Centripetal force would cause the planet to fly off into space, while gravity would cause planets to be pulled into the sun. It is the balance of these two forces that keep planets in their orbits. ____________________________________ Newton's 2nd Law states that a body in motion, tends to remain in motion with a uniform velocity. That means that unless there is some sort of outside force, an object will continue to move in a straight line at a constant speed. Gravity is the "outside force" than bends the moving object away from its straight path into an orbit. Orbits are a balance between the attractive force of gravity and the momentum of a moving body. It's a delicate balance; if the object (be it moon, satellite or planet) is moving too fast, it will fly out into space, and if it is moving too slowly it will fall in toward the primary body.
