The question is meaningless
The force of gravity is positive; there is no negative gravity.
You hold an object; then you release it, and it falls to the ground.You hold an object; then you release it, and it falls to the ground.You hold an object; then you release it, and it falls to the ground.You hold an object; then you release it, and it falls to the ground.
The acceleration is still 9.8 m/s2 but the force applied by gravity is counteracted by the ground.
The energy of the charge becomes greater than the insulating value of whatever separates the charge from its ground point.
If you mean acceleration due to gravity it is ~9.8m/s2
The acceleration due to gravity on the surface of Earth is approximately 9.81 m/s^2. This value represents the rate at which an object falls freely under the influence of gravity and is a constant value near the Earth's surface.
The speed of a falling object keeps changing as it falls. If an object falls 250 feet to the ground and there is no air, then it takes about 4 seconds to fall, and it hits the ground at about 86.5 miles per hour (127 fps). If the object falls through air, then the speed it picks up depends on its weight and shape ... a sailplane falls slower through air than a rock does, but take away the air, and a rock and a feather fall together.
Acceleration due to gravityThe acceleration produced in the motion of a body under gravity is called Acceleration.
The specific gravity value range for normal soils typically falls between 2.60 to 2.70. This range may vary slightly depending on the composition and characteristics of the soil. Specific gravity is a measure of the density of a material compared to the density of water.
The acceleration due to gravity is a constant value at a given location, approximately 9.81 m/s^2 on Earth. As such, the speed at which an object falls will increase at a constant rate due to this acceleration until it reaches terminal velocity or encounters other forces like air resistance. So, while the acceleration and speed are related, they are not always the same value throughout the falling process.
The numerical value in meters per second squared of the acceleration of an object experiencing true free fall is approximately 9.81 m/s^2. This value represents the acceleration due to gravity acting on the object as it falls under the influence of gravity alone.
The value of gravity in CGS units is approximately 980 cm/s^2.
