If a reaction both releases heat and increases entropy, it will always be spontaneous (have a negative ∆G), regardless of temperature. Similarly, a reaction that both absorbs heat and decreases entropy will be non-spontaneous (positive ∆G) at all temperatures.

The value of G is maximum at the poles. This is due to the closeness between the poles and the center of the earth.

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G (capital G). The relation between G and g is not proportional.

The acceleration due to gravity (g) is approximately a constant for objects relatively close to the Earth’s surface. By substituting in values for the mass and radius of the Earth, you can calculate the value of the gravity constant at the Earth’s surface. …

The direction of acceleration due to gravity is always towards earth, irrespective of the direction of motion of a body.

The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.

Its SI unit is m/s2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2….
