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 in newtons (N), m is mass in kilograms (kg), and a is acceleration in meters per second squared (m/s²).
The calculator uses Newton's second law equation:
Where:
Explanation: The equation shows that force equals mass multiplied by acceleration. This fundamental principle governs the motion of objects under the influence of forces.
Details: Calculating force is essential in physics, engineering, and everyday applications. It helps determine the amount of force needed to move objects, design structures, analyze motion, and understand the relationship between mass, acceleration, and applied forces.
Tips: Enter mass in kilograms and acceleration in meters per second squared. Both values must be positive numbers. The calculator will compute the resulting force in newtons.
Q1: What are the units of 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 be used for gravitational force?
A: Yes, for objects in free fall near Earth's surface, acceleration due to gravity is approximately 9.8 m/s².
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 force?
A: For the same acceleration, greater mass requires greater force. Mass and force are directly proportional when acceleration is constant.
Q5: What are practical applications of this calculation?
A: Used in vehicle design, sports science, construction engineering, rocket propulsion, and understanding everyday motions like pushing a cart or throwing a ball.
