Answer 2

Finding the Value of Free Fall Acceleration (Gravity)

To find the value of free fall acceleration (gravity), you can use the formula g = G * M / R^2, where: - g is the acceleration due to gravity - G is the gravitational constant - M is the mass of the celestial body - R is the distance from the center of the celestial body to the object in free fall

The value of the gravitational constant G is approximately 6.67259 × 10^(-11) m^3 kg^(-1) s^(-2).

The mass of the Earth (M) is approximately 5.972 × 10^24 kg.

The radius of the Earth (R) is approximately 6,371 kilometers (6.371 × 10^6 meters).

Using these values, you can calculate the acceleration due to gravity (g) at the surface of the Earth.

Calculation Example

Using the formula g = G * M / R^2: - G = 6.67259 × 10^(-11) m^3 kg^(-1) s^(-2) - M = 5.972 × 10^24 kg - R = 6.371 × 10^6 meters

Substitute these values into the formula: ``` g = (6.67259 × 10^(-11) m^3 kg^(-1) s^(-2) * 5.972 × 10^24 kg) / (6.371 × 10^6 meters)^2 ``` After performing the calculation, the value of g at the surface of the Earth can be determined.

Conclusion

By using the formula for gravitational acceleration and the known values for the Earth's mass and radius, you can find the value of the acceleration due to gravity at the surface of the Earth.
