Gravity, mainly. The Sun attracts the planets, and - to a lesser degree - the planets attract one another.

If the force of gravity suddenly stopped acting on the planets they would do what?
Gravity is what keeps the planets going in their orbits. If gravity just stopped, then the planets would go flying in a straight line tangent to their orbit.
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.
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 part does gravity play in the paths of the planets?
Gravity is the force which directs the path of the planets.
What outside force prevents the planets from moving in a straight line into space?
The force of gravity.
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.
Why do Newton's laws show a force must be acting on the planets?
That is because planets don't move in a straight line. Thus, there velocity changes; and changing the velocity requires a force.
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.
What is the force acting on flywheel?
The force acting on flywheel is called centrifugal force.
Can a force acting perpendicular on a body cancal a force which is acting horizontally on the same body?
no. a force acting perpendicularly on a body cannot cancel a force which is acting horizontally on the same body.!!!!
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.
Are acting on the pen?
The Forces acting on the pen are first the downward force called gravitational force and the upward force is the tension force.
What force keeps the planets in rotation?
The force that keeps all of our planets in rotation is gravity.
