Question

derive 'g' from the chapter gravitation​

Answer 1

Answer:

g is the local acceleration due to gravity between 2 objects. ... You get this value from the Law of Universal Gravitation. Force = m*a = G(M*m)/r^2. Here you use the radius of the earth for r, the distance to sea level from the center of the earth, and M is the mass of the earth.

dear sister do you give me brainliest answer

Answer 2

Answer:

g is the local acceleration due to gravity between 2 objects. ... You get this value from the Law of Universal Gravitation. Force = m*a = G(M*m)/r^2. Here you use the radius of the earth for r, the distance to sea level from the center of the earth, and M is the mass of the earth.

To calculate the force of gravity of an object, use the formula: force of gravity = mg, where m is the mass of the object and g is the acceleration of the object due to gravity. Since g is always 9.8 m/s^2, just multiply the object's mass by 9.8 and you'll get its force of gravity!
