∙ 7y agoIf the force moving an object points partially in the opposite direction of the object's motion, work is considered to be negative. This is because the force is acting against the direction of motion, reducing the overall work done on the object.
When the force acting on an object points at least partially in the direction of motion, the work done is considered to be positive. This is because the force is helping to move the object in the same direction as its motion, resulting in a positive work output.
If a particle is not moving towards the negative x-direction, it means that the net force acting on the particle is not causing it to accelerate in that direction. This could be due to the absence of a force in that direction or other forces balancing out the force pulling it in the negative x-direction. Inertia may also be a factor if the particle is already in motion and no new forces are acting on it in the negative x-direction.
In a coordinate system, positive force is typically defined as acting in the direction of the positive axis. For example, in a one-dimensional system, positive force would be in the positive direction of the axis, while negative force would be in the negative direction.
The particle may not be moving towards the negative x-direction due to the presence of forces acting on it in the opposite direction, or because the initial velocity is in the positive x-direction. It could also be confined to move in a different direction due to external constraints or boundaries.

The term, 'negative voltage', refers to its direction and has nothing to do with 'negative' in the 'charge' sense. It's used to indicate the direction in which a voltage is acting in relation to another voltage ('positive' if acting in the samedirection; 'negative' if acting in the opposite direction). So your question is confusing: 'negative' in relation to what?
A negative force. Since the force added in the opposite direction works against the original force, you would subtract the added force from the original force. Since subtracting a positive is the same thing as adding a negative, this force would be considered negative to the positive direction.

It is the same as adding a positive and adding a negative number
You take their algebraic sum - that is, their sum taking account of the direction. All forces acting in one direction are considered to be positive while those acting in the opposite direction are all negative.

When a vector is multiplied by a negative number, it changes direction by 180 degrees but keeps the same magnitude. Therefore, a vector initially acting at 90 degrees would end up acting at 270 degrees (or -90 degrees) after being multiplied by a negative number.
Yes, negative acceleration occurs when an object is slowing down due to a force acting in the opposite direction of its velocity. This is commonly referred to as deceleration.
