Why the partical is not moving toward negative x-direction?
Centripetal force is a force that makes a body follow a curved path: it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path. - See more at: http://www.chacha.com/question/what-is-the-path-of-a-moving-body-whose-acceleration-is-constant-in-magnitude-at-all-times-and-is-perpendicular-to-the-velocity#sthash.pqrkWxfT.dpuf
Negative speed indicates that the ball is moving in the opposite direction of its initial motion. When the ball falls back towards the earth, its speed is negative because it is moving in the opposite direction of its upward motion.
The convection zone of the sun contains hot gas moving up toward the surface and cooler gas moving down toward the center. This zone is located above the radiative zone and is responsible for transporting heat from the sun's core to its surface through the motion of plasma currents.
The electric field around a negative charge radiates outward, with field lines directed toward the charge. This means that a positive test charge placed in this field would be attracted toward the negative charge. The strength of the field decreases with distance from the negative charge.
The Lorentz force, F = q(v x B), where q = electric charge, v = velocity of the charge particle, and B = magnetic field.The direction of the charge particle is determined by v. F, v, and B are vectors, and follow the right-hand rule. First, point your right arm straight in the direction the particle is traveling, palm/hand flat with the thumb pointing at a right angle to the other 4 fingers; second, curl your right hand (bend at the wrist) toward where the magnetic field is pointing. The thumb indicates the direction of the force.For example, assume the magnetic field is pointing perpendicularly out of this page (a plane) toward you. Assume the charge particle carries a positive charge and is traveling up the page in the beginning. Then the force acts on the particle as a centripetal force and pulls the particle toward the right. The net result is that, in an ideal situation, the particle rotates in a clockwise direction on the plane. A negative particle will do so in a counterclockwise fashion.
Chemotaxis - this is the general term for bacterial motility when sensing a compound in the environment. If moving toward it is called positive chemotaxis, if away from it is negative chemotaxis.

The electrical charge on the plate that causes the beam to bend toward it is negative. When a charged particle or beam, which is typically positive, moves through an electric field created by the negatively charged plate, it experiences an attractive force toward the plate. This results in the beam bending toward the plate due to the influence of the electric field.

As you move to the left on a number line, negative numbers become smaller in value. This means that each step left represents a decrease in the number, moving toward more negative values. For example, moving from -2 to -3 means you are decreasing the value. Thus, the further left you go, the larger the absolute value of the negative number, indicating a lower numerical value.
Due to the doppler effect, objects moving toward us will be slightly more red than what they actually are, and objects moving away will be slightly more blue. Think of it like a siren coming toward you and moving away from you. If it is moving toward you, it will be slightly higher than what it really sounds like. If it is moving away it will have a slightly lower pitch.

Since we are always in motion and we have reason to believe that there are many black holes in the universe, there is bound to be one in the direction that we are moving. So, yes, I am moving toward a black hole. As are you.
you can't see it moving because your moving with it
