10 Famous Maths Equations. I G is a universal constant whereas g is a variable constant. Gravity Formula Gravity is the Force of attraction between two objects times the gravitational constant and inversely related to the square of the distance between the objects.
The equation for universal gravitation thus takes the form.
G 98 ms 2. H thVt gt where h 0 is the initial height of the ball in meters V is the initial speed in meterssecond and g is the acceleration of gravity in meterssecond 2. In symbols the magnitude of the attractive force F is equal to G the gravitational constant a number the size of which depends on the system of units used and which is a. The formula is F G m sub 1 m sub 2 r 2 where F is the force of attraction between the two bodies G is the universal gravitational constant m sub 1 is the mass of the first object m.
