You can use different units, but then the numerical value of the constant also changes. You need to know the units, in order to use the numerical value correctly.Mohamad said:We say the unit of gravitational costant is m3/kg.s2, but what does it mean?
The unit of gravitational constant is Newtons per square meter per kilogram squared (N·m^2/kg^2).
Gravitational constant is important because it is a fundamental constant in physics that helps us understand the force of gravity between two objects.
Gravitational constant is calculated by measuring the force of gravity between two objects and their masses, and then using the formula G = F·r^2/m1m2, where G is the gravitational constant, F is the force of gravity, r is the distance between the two objects, and m1 and m2 are the masses of the objects.
The value of gravitational constant is approximately 6.674 × 10^-11 N·m^2/kg^2.
Gravitational constant affects everyday life by determining the strength of gravity between objects, which is essential for understanding the motion of planets, stars, and other celestial bodies, as well as for practical applications such as space travel and satellite communications.
