Force Calculator: F=ma

Newton's laws of motion.

Force causes acceleration. F=ma.

Newton's Second Law

F=m×a. Newtons (N)=kg×m/s².

Types

  • Gravity: F=mg (9.8m/s²)
  • Friction: F=μN
  • Spring: F=-kx

Three Laws

  1. Inertia
  2. F=ma
  3. Equal and opposite reaction

Frequently Asked Questions

Unit of force?
Newton (N)=kg×m/s².
Mass vs weight?
Mass=amount(kg). Weight=gravity force(N). Weight=mg.
Net force?
Add as vectors. Same direction add, opposite subtract.
