What is Newton's second law?

F = m a. Force is mass times acceleration.

How for multiple forces?

Vector sum of all forces = net force, then a = F_net / m.

Newton's Second Law

Mass (m)

Acceleration (a)

m/s²

This law states that the force acting on an object is equal to the mass of that object times its acceleration.

Force Formula:

Force causes acceleration according to Newton’s laws. The SI unit is the newton (N).

A 5 kg mass accelerates at 1.4 m/s²: F = 5 × 1.4 = 7 N.

Net vs. applied?
Net force is the vector sum of all forces acting.

Units?
1 N = 1 kg·m/s².
