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 forms the basis of classical mechanics.
The calculator uses Newton's Second Law equation:
Where:
Explanation: The equation shows that acceleration increases with greater force and decreases with greater mass, following a linear relationship.
Details: Calculating acceleration is essential in physics, engineering, and various real-world applications including vehicle design, sports science, and space exploration. It helps predict object motion and design systems with desired performance characteristics.
Tips: Enter force in newtons (N) and mass in kilograms (kg). Both values must be positive numbers greater than zero. The calculator will compute the acceleration in meters per second squared (m/s²).
Q1: What is the relationship between force, mass, and acceleration?
A: Acceleration is directly proportional to force and inversely proportional to mass. Doubling the force doubles acceleration, while doubling the mass halves acceleration.
Q2: What units should I use for accurate calculations?
A: Use newtons (N) for force and kilograms (kg) for mass to get acceleration in meters per second squared (m/s²).
Q3: Can this calculator be used for objects in free fall?
A: Yes, for free fall near Earth's surface, use weight (mass × 9.8 m/s²) as the force to calculate gravitational acceleration.
Q4: What if multiple forces act on an object?
A: Use the net force (vector sum of all forces) in the calculation. Consider both magnitude and direction of forces.
Q5: Does this equation work for all types of motion?
A: This equation applies to linear motion with constant mass. For rotational motion or variable mass systems, different equations are needed.
