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 = ma, where F is force, m is mass, and a is acceleration.
The calculator uses Newton's Second Law formula:
Where:
Explanation: The acceleration of an object depends on both the magnitude of the net force and the mass of the object. Greater force produces greater acceleration, while greater mass results in less acceleration for the same force.
Details: Calculating acceleration is fundamental in physics and engineering for understanding motion dynamics, designing vehicles and machinery, and solving real-world problems involving moving objects.
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 SI unit for acceleration?
A: The SI unit for acceleration is meters per second squared (m/s²).
Q2: Can acceleration be negative?
A: Yes, negative acceleration (deceleration) occurs when an object slows down, indicating the acceleration vector is opposite to the velocity vector.
Q3: 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 the acceleration, while doubling the mass halves the acceleration.
Q4: Does this formula work for all types of motion?
A: This formula applies to linear motion with constant mass. For rotational motion or variable mass systems, different equations are needed.
Q5: What are some practical applications of this calculation?
A: Used in vehicle design, rocket science, sports mechanics, industrial machinery design, and any scenario where motion dynamics need to be analyzed.
