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 describes the relationship between force, mass, and acceleration, forming the basis for classical mechanics.
Details: Understanding force calculations is essential in engineering, physics, and everyday applications. It helps in designing structures, analyzing motion, and solving practical problems involving moving objects.
Tips: Enter mass in kilograms and acceleration in meters per second squared. All values must be positive numbers greater than zero.
Q1: What are the units of force in this calculation?
A: The result is given in Newtons (N), which is the SI unit of force. 1 Newton equals 1 kg·m/s².
Q2: Can this calculator be used for any object?
A: Yes, Newton's Second Law applies to all objects, regardless of size, as long as we're working within classical mechanics (not relativistic speeds).
Q3: What if I have multiple forces acting on an object?
A: For multiple forces, you would need to calculate the net force (vector sum of all forces) before using this equation.
Q4: Does this account for friction or air resistance?
A: No, this calculator assumes ideal conditions without friction or air resistance. For real-world applications, additional factors may need consideration.
Q5: Can I calculate mass or acceleration if I know the other two values?
A: Yes, the equation can be rearranged: m = F/a or a = F/m. However, this calculator specifically calculates force given mass and acceleration.
