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 effects does gravity have on planets?
The same effect as it has on any other object. The gravitational field produces a force; this force, acting on a planet, will accelerate it - that is, it will change its velocity.
Does gravity affect your weight on different planets?
Yes, gravity affects your weight on different planets. Weight is a measure of the gravitational force acting on an object, so on planets with stronger gravity, you would weigh more, and on planets with weaker gravity, you would weigh less compared to your weight on Earth.
What keeps the planets and sun in orbit?
The question probably means "What keeps the planets in orbit around the Sun?" The answer to that is : The Sun's gravitational attraction provides the force needed to keep the planets in orbit. This force doesn't pull the planets any closer to the Sun, but it stops the planets moving away (at a tangent to their orbits) due to their own velocities.
What outside force prevents the planets from moving in a straight line into space?
The gravitational force produced by the sun keeps the planets in orbit around it. This force pulls the planets toward the sun, creating a continuous circular motion rather than a straight line out into space.
How could newton's first law of motion explain that a force is acting between the sun and its planets?
If no force, the planets would move in a straight line, not in a orbit around the sun.
What is caused by the gravitional force acting on mass?
The gravitational force acting on mass causes objects to be attracted towards each other. This force is responsible for keeping planets in orbit around the sun and objects on the Earth's surface.
What keeps the planets in the Sun's orbit?
Gravitational force, combined with the velocities of the planets. The force from the Sun is pulling the planets toward it, but the velocity of each planet is acting against this. The result is that the planets orbit the Sun. (The question is a bit mixed up, but it seems obvious what it's about.)

Outward force made by centrifugal force that keeps planets in orbit?
Centrifugal force doesn't exist, and there is no outward force acting on planets. The only force on them is the 'centripetal' one ... the gravitational force between each planet and the sun, that attracts the planet in the direction toward the sun. That's the only force required to keep a planet in orbit ... which is lucky, because it's the only force there is.
Which force affects the motion of planets?
The motion of the planets are governed by a number of factors: Gravity - The planets are being pulled towards the Sun in free fall. The velocity of the planets - This balances against the force of gravity opposing it and producing on balance the orbit. The mass of the planets. The effect of gravitational attraction between the planet and any satellites it has. The effect of gravitational attraction between the planets and other planets/dwarf planets etc.
Why do Newton's laws show a force must be acting on the planets?
Newton's laws of motion state that an object at rest remains at rest and an object in motion remains in motion unless acted upon by a force. Since planets are constantly moving in their orbits, the fact that they do not travel in a straight line but follow a curved path implies that a force, such as gravity, must be acting on them to keep them in orbit around the Sun.
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.
Is there g-force present in space?
Yes, there is g-force present in space. G-force refers to the force of gravity acting on an object, and even in space, objects are still affected by the gravitational pull of celestial bodies like planets and stars.
What is the force that keeps planets orbiting star and satellites orbiting planets?
The force is called gravity. It is a force that works both ways, i.e. when the Sun's gravity operates on a planet, there isan equal an opposite force acting the other way but the Sun is so massive it hardly moves, because force equals mass times acceleration, so if mass is large the acceleration is low.
Can a force acting perpendicular on a body cancal a force which is acting horizontally on the same body?
Yes, a force acting perpendicular to a horizontal force on a body can cancel out the horizontal force if the two forces are equal in magnitude and opposite in direction. This is known as the equilibrium condition, where the net force acting on the body is zero.
