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.

# The acceleration due to gravity at the equator?

about 9.795m/s 2 but 9.8m/s 2 is almost always used. Note: centripetal acceleration (from the earth's spin) cause apparent gravity to be about 0.3% less than actual gra

# 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*acc gra ) -mg is a constant so taking the gradient will give you zero. Therefore, your answer is

# Why is acceleration due to gravity negative?

It is negative if the upwards direction is defined as positive. Acceleration is downward.

# Can there be a positive acceleration and a negative acceleration?

Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Nega

yes, 9.81 m/s^2

# 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

# When is acceleration due to gravity positive and when is it negative?

It all depends on the sign conventions you give to the upward and downward directions. The choice is completely up to you. -- If you call the direction toward the cen

# Why acceleration due to gravity 'g' is taken as negative for bodies moving upward?

The acceleration due to gravity is a property of the Earth's massand radius, and of gravity itself, and doesn't depend on which way something ismoving. -- The acceleration pr
