Force Calculator
Calculate force, mass, and acceleration using Newton's laws
Newton's Second Law: F = m × a
F = Force (N), m = Mass (kg), a = Acceleration (m/s²)
Newton's Second Law of Motion
Newton's second law states that the force acting on an object equals the mass of the object multiplied by its acceleration. This is one of the most important laws in classical physics and is widely used in engineering and science.
F = m × a
Where: F = Force (Newton), m = Mass (kilogram), a = Acceleration (meter/second²)
Practical Examples
Example 1: Pushing a car
If the car's mass is 1000 kg and it accelerates at 2 m/s², the required force = 1000 × 2 = 2000 N.
Example 2: Lifting an object
To lift a 50 kg object with an acceleration of 9.8 m/s² (gravitational acceleration), you need a force = 50 × 9.8 = 490 N.
Important Information
- The base unit of force is the Newton (N), where 1 N = 1 kg·m/s²
- Force is a vector quantity, having both magnitude and direction
- When force is zero, the object is at rest or moving at constant velocity
- This formula can be used to calculate force, mass, or acceleration if the other two values are known
