Usually we use the acceleration due to gravity, g, in classroom problems:
- Fgravity = m g, where g ≈ 9.81 m/s² (commonly rounded to 9.8 m/s² or to 10 m/s² for rough estimates). Direction: downward.
If you meant Newton's gravitational constant (for F = G m1 m2 / r²), that is G ≈ 6.674×10⁻¹¹ N·m²/kg².
Which one does your class use (9.8 or 10), or did you mean G instead of g?
