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 are the potential consequences of a reversal in the Earth's gravity from positive to negative earth gravity?
A reversal in Earth's gravity from positive to negative could have catastrophic consequences. It could lead to mass destruction of infrastructure, loss of life, and disruption of ecosystems. The change in gravity would affect everything on Earth, causing chaos and instability.
Is the force of gravity on a projectile considered positive?
In physics, the force of gravity is typically considered a negative force because it acts in the opposite direction to the motion of the projectile. Gravity causes the projectile to decelerate and move downwards.
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.
When is acceleration due to gravity positive and when is it negative?
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.
Is the gravity value positive or negative when an object falls on the ground?
The force of gravity is positive; there is no negative gravity.
Would zero gravity be at the same height and positive gravity be pulling and negative gravity be pushing?
No
How do you make a positive versus a negative ion?
gravity
Can their be negative gravity?
Yes, there can be negative gravity. If a gravity is a pulling force then in the other hands a negative gravity would be a pushing force, in other words, the negative gravity would push us to wherever and the positive gravity on Earth would pull us.
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 a positive and negative tropisms?
A positive tropism is something that bends with gravity or bends towards the light or the roots grow towards water. A negative tropism does the exact opposite.
Is a positive plus a negative make a positive or a negative?
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Why is gravitational potential always negative?
because gravity is a force that acts down on an object. In physics up is positive and down is negative
How is dividing integers similar to multiplying integers with the resulting sign?
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
If a negative is divided by a positive is it negative?
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
