Negative feedback
When the body reacts to stop or work in the opposite direction of a stimulus, it is known as negative feedback. Negative feedback mechanisms help maintain homeostasis by reducing the effects of a stimulus to keep things within a normal range.
This phenomenon, known as the "motion aftereffect" or "direction aftereffect," occurs because the brain's neurons that respond to motion become fatigued after prolonged exposure to a moving stimulus in one direction. When the stimulus is removed, the neurons that respond to the opposite direction of motion become more active, creating the illusion that the image is moving in the opposite direction.
When studying the difference threshold, the stimulus that remains the same across trials is called the "standard stimulus." This is the reference point against which changes in the other stimulus, known as the "comparison stimulus," are measured. The difference threshold refers to the minimum amount of change required in the comparison stimulus for a participant to detect a difference from the standard stimulus.

To counteract forces in the opposite direction, you can apply an equal and opposite force to cancel it out. This principle, known as Newton's third law of motion, states that for every action, there is an equal and opposite reaction.
The force that pushes an object in the opposite direction of its motion is known as friction. Friction is the resistance that occurs when two surfaces come in contact and it acts in the direction opposite to the object's motion.
When a student leans on a wall, they experience a force pushing back on them in the opposite direction, known as the normal force.
An object accelerates in the direction opposite to its motion when a force acts in the opposite direction to its velocity. This is known as deceleration or negative acceleration, and it occurs when there is a force opposing the object's motion, causing it to slow down.
A pitched ball in baseball that curves in the direction opposite to that of a normal curve ball.
Forces that are equal in magnitude but opposite in direction. For example, if you push against a brick wall and it doesn't move or become deformed, then the brick wall is exerting an equal force against you.
Upthrust, also known as buoyancy force, acts opposite to the direction of gravity. It pushes objects upward when they are submerged in a fluid, such as water.
A force that works opposite to the direction of travel is known as friction. Friction opposes motion between surfaces in contact with each other, causing resistance that slows down or stops the movement of an object.
Actually, forces that are equal in size but opposite in direction are called balanced forces. Unbalanced forces are forces that are not equal in size and/or opposite in direction, resulting in a change in an object's motion.
