what is the difference between positive acceleration and?
603552
Positive acceleration is acceleration that has a direction pointing in the positive direction, while negative acceleration is an acceleration that has a direction pointing in the negative direction.

A positive coefficient for a material means that its resistance increases with an increase in temperature. ... A negative coefficient for a material means that its resistance decreases with an increase in temperature.

As nouns the difference between vibration and acceleration is that vibration is the act of vibrating or the condition of being vibrated while acceleration is (uncountable) the act of accelerating, or the state of being accelerated; increase of motion or action; as opposed to retardation or deceleration.

2. Positive Modulation • The amplitude of the carrier increases with increase in amplitude of the signal and vice versa. This is called “positive modulation”. ... Negative Modulation • The instantaneous amplitude of the carrier decreases with increase in instantaneous amplitude of the signal.

What is the difference between a positive and negative correlation? ... Positive correlation means that as one variable goes up, so does the other. Negative correlation means that as one variable goes up or down, the other goes the opposite way.

In Example A, the object is moving in the positive direction (i.e., has a positive velocity) and is speeding up. When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration.

When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration. In Example B, the object is moving in the negative direction (i.e., has a negative velocity) and is slowing down.

An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. How is this so? Consider the fact that acceleration is a vector that points in the same direction as the change in velocity.

The acceleration can only be denoted as positive acceleration and negative acceleration. As acceleration is a vector, it has magnitude and direction dependence. When we say deceleration, it means the speed is slowing down. ... The Retardation is used in general context, it also means same as deceleration.

But positive and negative do not represent the quality of the factor being added or removed. That factor can be pleasant or unpleasant. For instance, positive can be adding something unpleasant resulting in unpleasant feelings, while negative can be removing something unpleasant resulting in pleasant feelings.

In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up. When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object also has a negative acceleration.

The car is also decelerating: the direction of its acceleration is opposite to its direction of motion. (c) This car is moving toward the left, but slowing down over time. Therefore, its acceleration is positive in our coordinate system because it is toward the right.

Speeding Up and Slowing Down If the velocity and acceleration are in the same direction (both have the same sign - both positive or both negative) the object is speeding up. If the velocity and acceleration are in opposite directions (they have opposite signs), the object is slowing down.

answer: when an object moves in a straight line displacement in positive.this is positive displacement.when the initial and final position are same for an object,then it has zero displacement.displacement can never be negative.

The difference between negative and positive feedback systems is that in negative feedback systems, the response reverses the original stimulus, but in positive feedback systems, the response enhances the original stimulus.

That means that the direction of the acceleration determines whether you will be adding to or subtracting from the velocity. Mathematically, a negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity.

As listed above, positive punishment involves adding something unpleasant to discourage a behavior. Positive reinforcement involves adding something pleasant to encourage a behavior.
