Understanding the Calculation of g: Acceleration Due to Gravity Explained
Learn how g, the acceleration due to gravity, is calculated, including its value and determination methods.
609 views
'g' is calculated based on the acceleration due to gravity on a given object. The standard value for g is approximately 9.81 m/s² on Earth's surface. This value is derived by considering the Earth's mass, radius, and the universal gravitational constant. For practical measurements, g can be determined using pendulum experiments or free-fall equations in physics.
FAQs & Answers
- What is the standard value of g? The standard value of g is approximately 9.81 m/s² at Earth's surface.
- How do pendulum experiments determine g? Pendulum experiments measure the time period of oscillation to calculate g based on known length and gravitational principles.
- What factors affect the value of g? The value of g varies slightly due to altitude, Earth's rotation, and local geological variations.
- Is g the same everywhere on Earth? No, while the standard value is 9.81 m/s², local values can vary due to factors like altitude and latitude.
