Force Formula:
From: | To: |
Definition: This calculator computes the force acting on an object using Newton's Second Law of Motion (F = ma).
Purpose: It helps physics students, engineers, and scientists determine the force required to accelerate a mass or the force resulting from acceleration.
The calculator uses the formula:
Where:
Explanation: The force acting on an object equals its mass multiplied by its acceleration.
Details: Understanding force is fundamental in physics, engineering design, vehicle safety, and many mechanical applications.
Tips: Enter the mass in kilograms and acceleration in m/s² (default 9.81 for Earth's gravity). All values must be > 0.
Q1: What is the standard unit for force?
A: The Newton (N) is the SI unit of force, where 1 N = 1 kg·m/s².
Q2: What's Earth's gravitational acceleration?
A: Approximately 9.81 m/s² at sea level (varies slightly by location).
Q3: Can I calculate mass or acceleration instead?
A: Yes, by rearranging the formula: m = F/a or a = F/m.
Q4: How does this relate to weight?
A: Weight is the force of gravity on an object (W = m × g, where g is gravitational acceleration).
Q5: What if multiple forces act on an object?
A: Use vector addition to find the net force before applying F = ma.
