## What is F Gm1m2 r2?

• Newton’s Law of Gravita- tion states that two objects with masses m1 and m2, with a distance r between their cen- ters, attract each other with a force F given by: F = Gm1m2/r2 where G is the Universal Grav- itational Constant (equal to: 6.672 x 10-11Nm2/kg2).

What is MLT physics?

Any mechanical quantity can be expressed in terms of three fundamental quantities, mass, length and time. We use the symbols MLT (not in italics) to indicate the fundamental dimensions of mass, length and time.

### How do you find the dimensional formula for gravitational force?

∴ The dimensional formula of force = M 1 L 1 T -2 . . . . (2) Or, G = [M 1 L 1 T -2 ] × [L] 2 × [M] -2 = [M -1 L 3 T -2 ]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.

What is Newton’s universal law of gravitation?

Sir Isaac Newton’s universal law of gravitation (F=Gmm/r2) is an equation representing the attractive force (F) of two masses (m) separated at distance (r). It was first published as a part of Newton’s works on classical mechanics in the late 1600s.
