When can you used the positive acceleration due to gravity and negative acceleration due to gravity?

If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.

When is the term negative acceleration used?
The term negative acceleration is used when something is slowing down from its motion. When pushing the brakes the car will negatively acceleration to slow down .
What letter is used to represent the acceleration due to gravity?
g. lower case.
Why is the direction of free-fall acceleration usually negative?
Free fall is defined as ''the motion of an object undergoing an acceleration of g'' As we know acceleration is a vector quantity and 'g' acts vertically downwards. Also, the only force acting on an object in free fall is its weight and weights acts downwards.
What things are pendulums used for?
It can be used to measure g's [ the acceleration due to gravity and it can be used also to prove that the Earth spins.
What is the derived unit for gravity?
If you mean the gravitatioal field - other options are possible - units of acceleration are used for that. The force of gravity, of course, is expressed in units of force.
What is the meaning of acceleration?
of Accelerate
When is the term negative acceleration used?
The term negative acceleration is used when something is slowing down from its motion. When pushing the brakes the car will negatively acceleration to slow down .
Where can the concept of the center of gravity be used?
Acceleration of rotating objects
Is a negative object attracting a neutral object considered magnetism?
"Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces.
Why do scientist often refer to deceleration as negative acceleration?
Deceleration is often referred to negative acceleration because deceleration is not AA commonly used word.
What signs are used when mulitiplying and dIviding integers would the signs be the same and the answer negative?
positive x positive = positive negative x negative = positive positive x negative = negative negative x positive = negative The same rules apply for dividing, since dividing is actually multiplying by the reciprical.
What letter is used to represent the acceleration due to gravity?
g. lower case.
What do you disconnect first positive or negative?
Positive, because the negative terminal is usually used as the ground plane.
What is the significance of the simple pendulum?
The simple pendulum can be used to determine the acceleration due to gravity.
Why is the direction of free-fall acceleration usually negative?
Free fall is defined as ''the motion of an object undergoing an acceleration of g'' As we know acceleration is a vector quantity and 'g' acts vertically downwards. Also, the only force acting on an object in free fall is its weight and weights acts downwards.
What things are pendulums used for?
It can be used to measure g's [ the acceleration due to gravity and it can be used also to prove that the Earth spins.
What formula is used in Archimedes' principle?
Archimedes principle - weight of the liquid displaced by the object= buoyant force weight=mass x acceleration due to gravity =volume x density x acceleration due to gravity
