negative feedback
Positive feedback amplifies a response in the same direction, such as the release of oxytocin during childbirth. Negative feedback regulates a response by counteracting changes, like temperature regulation in the body.
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.

The direction of current flow is defined as the direction positive charge carriers would flow, which is opposite to the actual movement of electrons (negative charge carriers) in a wire. Electrons flow from the negative terminal of a power source to the positive terminal, while conventional current flows from the positive terminal to the negative terminal.
Feedback can be both negative and positive. Negative feedback occurs when the body's response counteracts the stimulus, helping to maintain homeostasis. Positive feedback amplifies the stimulus, leading to a larger response.
You can consider any direction as positive, and the opposite direction as negative. However, in this case it is customary to call a gain "positive", and a loss "negative".
In this scenario, the velocity is negative if the object is moving in the opposite direction of the positive direction.
Is the clotting of blood an example of positive or negative feedback?
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
If you define one direction (for example, north) as positive, then the opposite direction is negative.
Velocity can have positive or negative value depending on the direction of the change in position. Positive velocity indicates motion in one direction, while negative velocity indicates motion in the opposite direction.
The opposite of praising is criticizing - offering negative feedback or disapproval instead of positive reinforcement or admiration.
In physics, displacement can be either positive or negative depending on the direction of the movement. Positive displacement indicates movement in one direction, while negative displacement indicates movement in the opposite direction.
An object can have negative momentum if it is moving in the opposite direction to a chosen positive direction. Momentum is a vector quantity that considers both the mass and velocity of an object, so moving in the opposite direction as chosen positive direction can result in negative momentum.
because current flows in the opposite direction of the flow of electron.since electrons are negatively charged particle they moves towards the positive and hence current flows in the opposite direction to the flow of electrons (that is from positive to negative)
Yes, velocity can be negative in physics when an object is moving in the opposite direction of the chosen positive direction.
