The acceleration due to gravity, often denoted as “g,” is a fundamental physical constant that represents the acceleration experienced by an object due to the gravitational attraction of the Earth or another celestial body. In aircraft design and aviation, it is crucial for understanding weight, lift, and various other aspects of flight.
The formula and definition of acceleration due to gravity are as follows:
- “g” is the acceleration due to gravity.
- “G” is the universal gravitational constant (approximately 6.674 × 10^(-11) N(m/kg)²).
- “M” is the mass of the Earth (approximately 5.972 × 10^24 kilograms).
- “R” is the radius of the Earth (approximately 6,371 kilometers).
