Force Formula:
From: | To: |
Definition: Newton's Second Law of Motion states that force equals mass times acceleration (F = m × a).
Purpose: This fundamental physics equation calculates the force needed to accelerate a mass or the force resulting from an acceleration.
The calculator uses the formula:
Where:
Explanation: The mass of an object multiplied by its acceleration gives the force acting on or produced by that object.
Details: Understanding force is crucial in physics, engineering, and everyday applications from vehicle safety to building design.
Tips: Enter the mass in kilograms and acceleration in m/s² (default 9.8 m/s² for Earth's gravity). All values must be > 0.
Q1: What is a Newton (N)?
A: One Newton is the force needed to accelerate 1 kg of mass at 1 m/s².
Q2: Why is Earth's gravity 9.8 m/s²?
A: This is the average acceleration due to gravity at Earth's surface.
Q3: Can I calculate weight with this?
A: Yes! Weight is the force of gravity on an object (F = m × 9.8).
Q4: How do I convert Newtons to pounds?
A: 1 N ≈ 0.2248 pounds-force. Multiply Newtons by 0.2248.
Q5: What if acceleration is negative?
A: Negative acceleration (deceleration) still produces force, just in the opposite direction.
