What is the value of the gravitational constant (G) in SI units? (2023)
Step 1: Understand that the gravitational constant (G) is a fundamental physical constant used in the calculation of gravitational force between two masses.
Step 2: Know that G is measured in specific units, which are Newtons (N) for force, square meters (m²) for distance, and kilograms (kg) for mass.
Step 3: The value of G is defined as 6.67 x 10^-11 when expressed in SI units.
Step 4: Remember that this value is important in physics for calculating how objects attract each other due to gravity.
