Accelaration Gravity

In summary, the formula for calculating gravity acceleration is g = G * (M / r^2). The acceleration due to gravity can be measured using a pendulum, a spring scale, or by dropping objects and recording their free fall time. The acceleration due to gravity can be affected by the mass of the celestial body, the distance from the center of the body, and the gravitational constant. On Earth, the acceleration due to gravity varies slightly depending on location and altitude, with an average value of 9.8 m/s^2. It is related to weight through the formula F = m * g, meaning that an object's weight can change depending on the acceleration due to gravity of its location.

Didn't you ask this same question about a week ago? Check that thread.

If you are looking for the local variation in g (from its average of 9.8 m/s²) due to geological structures or altitude: that would be measured, not calculated.

1. What is the formula for calculating gravity acceleration?

The formula for calculating gravity acceleration is g = G * (M / r^2), where g is the acceleration due to gravity, G is the gravitational constant (6.67 x 10^-11 N*m^2/kg^2), M is the mass of the celestial body (such as Earth), and r is the distance between the center of the body and the object.

2. How do you measure the acceleration due to gravity?

The acceleration due to gravity can be measured using a pendulum, a spring scale, or by dropping objects and recording their free fall time.

3. What factors affect the acceleration due to gravity?

The acceleration due to gravity can be affected by the mass of the celestial body, the distance from the center of the body, and the gravitational constant.

4. How does the acceleration due to gravity vary on Earth?

The acceleration due to gravity varies slightly on Earth depending on the location and altitude. The average value is 9.8 m/s^2, but it can range from 9.78 m/s^2 at the equator to 9.83 m/s^2 at the poles.

5. How is the acceleration due to gravity related to weight?

The acceleration due to gravity is related to weight through the formula F = m * g, where F is the force of gravity, m is the mass of the object, and g is the acceleration due to gravity. This means that the weight of an object will change depending on the acceleration due to gravity of the location it is in.
