Frequently Asked Questions
Newton's second law of motion states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).
Force is measured in Newtons (N) in the SI system. One Newton is the force required to accelerate a 1 kg mass by 1 m/s².
Rearrange Newton's second law to m = F / a. Divide the applied force in Newtons by the acceleration in m/s² to get mass in kilograms.

About This Calculator
Calculate net force, mass, or acceleration using Newton's second law of motion (F = ma).
How to Use the Force Calculator
- 1Enter the mass of the object in kilograms (kg) in the Mass field.
- 2Enter the acceleration of the object in meters per second squared (m/s²) in the Acceleration field.
- 3The calculator instantly computes the net force using Newton's Second Law: F = m × a.
- 4To calculate weight (gravitational force), use the default acceleration of 9.8 m/s² (Earth's gravity).
Newton's Second Law Formula Explained
Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The mathematical expression is F = m × a, where F is the net force in Newtons (N), m is the mass in kilograms (kg), and a is the acceleration in meters per second squared (m/s²).
This law is foundational to classical mechanics and applies to all macroscopic objects. When the acceleration equals gravitational acceleration (g ≈ 9.81 m/s²), the formula calculates the object's weight — the gravitational force exerted on it by Earth. The formula can be rearranged to solve for any of the three variables: m = F/a or a = F/m.
Worked Force Calculation Examples
Example 1: Force on a Moving Car
- A car has a mass of 1,500 kg and accelerates at 3 m/s².
- Apply the formula: F = m × a = 1,500 × 3.
- Multiply: 1,500 × 3 = 4,500 N.
The net force on the car is 4,500 Newtons (4.5 kN).
Example 2: Weight of an Astronaut on the Moon
- An astronaut has a mass of 75 kg. The Moon's gravitational acceleration is 1.62 m/s².
- Apply the formula: F = m × g = 75 × 1.62.
- Multiply: 75 × 1.62 = 121.5 N.
The astronaut weighs 121.5 N on the Moon, compared to ~735 N on Earth.
Frequently Asked Questions About Force
What is the difference between mass and weight?
Mass is the amount of matter in an object, measured in kilograms, and it stays the same everywhere. Weight is the gravitational force acting on that mass (W = mg), measured in Newtons, and it varies depending on the gravitational field strength of the planet or celestial body.
Can force be negative?
Yes. Force is a vector quantity, meaning it has both magnitude and direction. A negative force value simply indicates the force acts in the opposite direction to the chosen positive reference direction — such as friction opposing motion or deceleration.
What happens when multiple forces act on an object?
When multiple forces act on an object, you must find the net force — the vector sum of all individual forces. If forces act along the same line, add those in the same direction and subtract those in the opposite direction. The net force determines the object's acceleration via F_net = ma.
