Calcolatrice forza

Calcola forza, massa o accelerazione usando la Seconda Legge di Newton (F=ma). Calcolatore di fisica online gratuito.

Cos'e' Calcolatrice forza?

A force calculator applies Newton's Second Law of Motion to calculate the relationship between force, mass, and acceleration. This fundamental principle of physics states that the force acting on an object equals its mass multiplied by its acceleration. Whether you're studying physics, designing mechanical systems, or solving engineering problems, understanding force calculations is essential.

Force is measured in Newtons (N) in the metric system and pounds-force (lbf) in the imperial system. One Newton is the force needed to accelerate one kilogram of mass at one meter per second squared. This calculator helps you determine any one of the three variables (force, mass, or acceleration) when you know the other two.

Formula

F = m × a (Force = Mass × Acceleration)

m = F / a (Mass = Force ÷ Acceleration)

a = F / m (Acceleration = Force ÷ Mass)

Where: F = Force (Newtons), m = Mass (kg), a = Acceleration (m/s²)

Esempio

A car with a mass of 1,500 kg accelerates at 3 m/s². The force required is F = 1,500 × 3 = 4,500 N. If the same car experiences a braking force of 6,000 N, its deceleration is a = 6,000 / 1,500 = 4 m/s².

Domande Frequenti

What is a Newton?

A Newton (N) is the SI unit of force. One Newton is the force needed to accelerate 1 kg of mass at 1 m/s². It's named after Sir Isaac Newton, who formulated the laws of motion.

What's the difference between mass and weight?

Mass is the amount of matter in an object (measured in kg). Weight is the force of gravity on that mass (measured in N). On Earth, weight = mass × 9.81 m/s² (gravity).
