# What is the rate of acceleration due to gravity?

32 feet per second squared. 9.8 meters per second squared.

# What is the acceleration due to gravity on Neptune?

# What is acceleration due to gravity on earth?

9.8 meters/seconds 2 or 32.3 feet/seconds 2

# 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…vity (about 9.767m/s 2 ) at the equator you can find the acceleration of gravity on any planet by the equation: a=G(M/R 2 ) where 'a' is the acceleration due to gravity, G is the gravitational constant (about .0000000000667), M is the mass of the earth ( or other planet), and R is the radius of the earth (or other planet) References: A.P.

# 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… zero. Now, if you took the gradient of velocity , your answer would be a negative constant.

# 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…tive acceleration is usually called deceleration.

# How can you define acceleration due to gravity?

yes, 9.81 m/s^2

# What is acceleration due to gravity on Jupiter?

We can calculate the gravity on any planet or star by using this formula g = GM/r 2 where M is mass of the planet or star G is universal gravitational constant g is …acceleration due to gravity & r is the radius of the planet or star. Mass of Jupiter is 1.9 X 10 27 kg Radius of Jupiter is 7 x 10 7 m Putting the values in formula we get g = (6.673 x 10 -11 ) x (1.9 x 10 27 )/(7 x 10 7 ) 2 = 26m/s 2

# What is the acceleration due to gravity on an asteroid?

Just like any other astronomical body that you might visit, the acceleration due to gravity on the asteroid's surface is going to depend on its mass, and on the distance b…etween your center of mass and the asteroid's center of mass. (I didn't want to say the asteroid's "radius", because many of them are notoriously unspherical and weird-shaped, like a big old Russet Burbank.)

# 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 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…ter of the Earth, downward into the mine, "positive", then the acceleration of gravity is always positive. -- If you call the direction away from the center of the Earth, upward into the sky, "positive", then the acceleration of gravity is always negative.

# 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…oduced by a force is always in the directionof the force, and the forces of gravity act along the line between the centers oftwo objects. -- One force of gravity acts on the body that's up in the air,pulling it ... and therefore accelerating it ... toward the center of the Earth, withacceleration equal to the body's weight / the body's mass =9.8 meters per second 2 . -- The other force of gravity acts on the Earth, pulling it ... andtherefore accelerating it ... toward the center of the body that's up in theair, with acceleration equal to Earth's weight / Earth'smass . In order to calculate that number, you have to know the Earth's weight. It's the same as theweight of the body that's up in the air, since the forces of gravity areequal in both directions. So once you know the weight of the body on Earth, youknow the weight of the Earth on the body, and you can calculate the Earth'sacceleration when they're falling toward each other.
