Acceleration due to gravity is negative when an object is moving up. Accl'n due to gravity is positive when an object is moving down (since gravity acts downwards on an object).
^Acceleration due to gravity is always negative, while the acceleration of the ball upward was positive due to what threw it, not gravity.
What else can I help you with?
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.
What is positive and negative acceleration?
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
Can a man in a parachute accelerate?
Yes. Acceleration can be positive or negative. When he jumps out of the airplane and is in free fall, he is accelerating in a downward direction, so his acceleration is negative. When he opens his parachute, he accelerates in an upward direction, so his acceleration is positive.
Why it is taken as negative when an object is thrown upwards against gravitation?
When we throw the object upwards we consider that upward direction as positive. Therefore, the velocity in that direction is positive but the acceleration due to gravity is in the opposite direction and so it is considered negative. But when the ball comes down again after reaching a certain height the velocity is in opposite direction to the earlier one and so the velocity now is negative as a result the acceleration is again negative.
What is equivalent of acceleration due to gravity?
The equivalent of acceleration due to gravity on the surface of the Earth is approximately 9.81 m/s^2.

How does the acceleration of gravity vary as one goes upward from the surface of the earth?
The farther away from an object on gets, the less powerful the gravitational pull by that object is. As one moves upward from the surface of the earth, the earth's gravitational pull has less of an effect. Since acceleration due to gravity is negative (-9.8 m/s2), the acceleration due to gravity will increase (the acceleration would decrease if you are considering falling down towards the earth to be positive, not negative velocity). This means that the object will not fall as fast, or that of the object is traveling upwards, it will not slow down as rapidly.
What is Saturn's value for acceleration due to gravity?
Saturn's acceleration due to gravity is approximately 10.4 m/s^2, which is about 1.1 times the acceleration due to gravity on Earth.
What force that can change when acceleration due to gravity changes?
I suppose you are asking about what forces change when acceleration due to gravity changes. In this case, the formula for forces concerning acceleration due to gravity is as such: fg=mg. When acceleration due to gravity(g) changes, it affects the force of gravity which is also known as the weight of the object. This is shown as fg.
When will one get a negative gradient for acceleration due to gravity experiment?
From Newton's Law, the force due to gravity is:F = -mg, (Force = -mass*accgra)-mg is a constant so taking the gradient will give you zero. Therefore, your answer is zero. Now, if you took the gradient of velocity, your answer would be a negative constant.
Will acceleration due to gravity change the weight of an object?
No, acceleration due to gravity does not change the weight of an object. Weight is determined by the mass of the object and the acceleration due to gravity in that location. The acceleration due to gravity affects the force with which an object is pulled toward the center of the Earth, leading to its weight.
What is accileration due to gravity on earth?
Acceleration due to gravityThe acceleration produced in the motion of a body under gravity is called Acceleration.
Explain the difference between positive and negative acceleration?
well the difference between positive and negative velocity would have to be that if your motion speeds up than you have a positive and when or if your motion slows down then you would have a negative accelerarion!!!!
