what is the difference between negative and positive acceleration?
75128
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.

The general principle for determining the acceleation is: If an object is slowing down, then its acceleration is in the opposite direction of its motion. This general principle can be applied to determine whether the sign of the acceleration of an object is positive or negative, right or left, up or down, etc.

Note that the average acceleration can be positive, negative, or zero. A negative acceleration is simply an acceleration in the negative direction. Keep in mind that although acceleration points in the same direction as the change in velocity, it is not always in the direction of the velocity itself.

Less than 5 to 10 percent of lightning strikes are positive. The rest are negative. ... Positive lightning carries a much greater charge and a longer flash duration than negative lightning, reaching up to 1 billion volts and 300,000 amps, compared with 300 million volts and 30,000 amps with negative lightning.

The difference between negative and positive motivation is the difference between surviving and living. If you are a positively motivated your action will most likely have a positive outcome. On the other, if you are negatively motivated, your action will have an undesirable negative outcome.

Positive vs. Negative Feedback. The key difference between positive and negative feedback is their response to change: positive feedback amplifies change while negative feedback reduces change. This means that positive feedback will result in more of a product: more apples, more contractions, or more clotting platelets ...

A negative ion is (larger/smaller) than its parent atom. ... A positive ion is (larger/smaller) than its parent atom. 6. As you go from left to right across a period, the ionization energy generally (decreases/increases).

Acceleration: The rate of change in the velocity of an object per unit time is referred as acceleration and the kind of motion is known as accelerated motion. The acceleration is positive when it is in the direction of velocity and negative when it is opposite to the direction of velocity.

The difference between a positive and a negative integer can be positive or negative. When you subtract a negative integer from a positive integer, the difference is always positive. Note: When you subtract a negative integer, the integer becomes positive.

In the figure below, both cars are accelerating because their speeds are changing. When a car's acceleration and velocity are in the same direction, the speed increases and the acceleration is positive. ... When a car is slowing down, the acceleration and velocity are in opposite directions. The acceleration is negative.

The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. ... The acceleration is negative when going down because it is moving in the negative direction, down.

Answer; -Positive feedback leads to system instability, while negative feedback leads to system stability.

The difference between two positive integers can be either positive, negative or zero. ... The difference between a positive and a negative integer can be positive or negative. When you subtract a negative integer from a positive integer, the difference is always positive.

The value of numbers get decreases by moving towards left from 0 while it increases while moving right to zero. Hence Positive Numbers (including Zero too) are always Greater than the Negative numbers. Though, 2 is greater than 1, but negative sign before 2 ( i.e. - 2) makes it smaller than 1.

If acceleration is in direction of velocity, the object speeds up. If acceleration and velocity are in opposite directions, the object slows down, and later reverses its velocity direction.

However, there is difference between literal and scientific meanings of these terms. In literal sense, acceleration is considered to describe an increase or positive change of speed or velocity. On the other hand, deceleration is considered to describe a decrease or negative change of speed or velocity.

Consider the two data tables below. In each case, the acceleration of the object is in the positive direction. 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.
