Newton's Second Law:
| From: | To: |
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 law is mathematically expressed as F = m × a, where F is force, m is mass, and a is acceleration.
The calculator uses Newton's Second Law equation:
Where:
Explanation: This fundamental physics equation allows you to calculate any one of the three variables if you know the other two. The relationship shows that force is the product of mass and acceleration.
Details: Understanding and calculating force is essential in physics, engineering, and everyday applications. It helps in designing structures, analyzing motion, solving mechanical problems, and understanding the fundamental principles of dynamics.
Tips: Enter any two known values (force, mass, or acceleration) and leave the third field empty or set to zero. The calculator will automatically compute the missing variable. All values must be positive numbers.
Q1: What are the SI units for force, mass, and acceleration?
A: Force is measured in Newtons (N), mass in kilograms (kg), and acceleration in meters per second squared (m/s²).
Q2: Can this calculator handle different unit systems?
A: This calculator uses SI units only. For other unit systems, convert values to SI units before calculation.
Q3: What is the relationship between force and acceleration?
A: Force and acceleration are directly proportional when mass is constant. Doubling the force doubles the acceleration.
Q4: How does mass affect acceleration?
A: Mass and acceleration are inversely proportional when force is constant. Doubling the mass halves the acceleration.
Q5: What are some real-world applications of this law?
A: Car safety design, rocket propulsion, sports mechanics, structural engineering, and understanding planetary motion.
