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. This fundamental principle describes the relationship between force, mass, and acceleration in classical mechanics.
The calculator uses Newton's Second Law equation:
Where:
Explanation: The equation shows that for a constant mass, acceleration increases linearly with net force. For a constant force, acceleration decreases as mass increases.
Details: Calculating acceleration is essential in physics, engineering, and various real-world applications. It helps predict object motion, design vehicles and machinery, understand planetary motion, and solve practical problems in transportation and sports science.
Tips: Enter net force in newtons (N) and mass in kilograms (kg). Both values must be positive numbers greater than zero. The calculator will compute acceleration in meters per second squared (m/s²).
Q1: What is the difference between net force and applied force?
A: Net force is the vector sum of all forces acting on an object, while applied force refers to a single force. Net force accounts for friction, gravity, and other opposing forces.
Q2: Why does mass affect acceleration?
A: Mass represents an object's resistance to changes in motion (inertia). More mass means more inertia, requiring more force to achieve the same acceleration.
Q3: What are typical acceleration values?
A: Car acceleration: 2-3 m/s², Free fall: 9.8 m/s², Sports car: 5-8 m/s², Space shuttle: 29 m/s² at launch.
Q4: Can acceleration be negative?
A: Yes, negative acceleration (deceleration) occurs when an object slows down. In vector terms, it means acceleration opposes the direction of motion.
Q5: How does this relate to everyday situations?
A: This principle explains why heavier objects require more force to move, why cars accelerate slower when loaded, and how rockets overcome gravity.
