A spinning top presses harder into the ground than when it is upright with just gravity operating on it and it's not rotating .What direction is the force that keeps you in circular motion in an orbiting spacecraft?
The primary direction of force is from the outside of the space station towards the center of the space station. It is the space station pushing against you that keeps you in a circular motion. It is not gravity.
If the space station was to suddenly disappear, you would continue in a strait line in the direction you were traveling at the moment the space station disappeared.
The friction of your contact with the space station continuously alters your direction so that you move in a circular motion.What direction is the force that keeps you in circular motion in an orbiting spacecraft?isn't that centripical force....spelling is wrong?What direction is the force that keeps you in circular motion in an orbiting spacecraft?
The force that keeps a space station orbiting is towards the point of greatest gravitational power. If you're orbiting the Earth, that point is approximately at the center of the Earth, and assuming the orbit is round, it will be in the middle of the orbit (an elliptical orbit will have this point nearer to one end, and the space station will be going faster at that end).
The force that keeps a space station revolving by itself, regardless of its orbit, goes in a different direction depending on where you are on the space station; it goes in a tangent from the circle that point makes around the space station's center of mass as it rotates.What direction is the force that keeps you in circular motion in an orbiting spacecraft?The direction would be towards the axis of rotation. In other words towards the center. This is usually called a centripetal force.What direction is the force that keeps you in circular motion in an orbiting spacecraft?
outward force. constantly changing. Inirtia is the resistance to a change in direction, therefore the "gravity" on a space station is created by the force constantly changing direction and therefore always going outward from the center of the rotation.
The instantaneous force is always at right angles to the instantaneous velocity.
In the case of an orbiting spacecraft, it's the force created by gravitational acceleration acting on the mass of the spacecraft.
