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 required to produce that acceleration.
Details: Understanding force is crucial in physics, engineering, vehicle design, construction, and many mechanical systems.
Tips: Enter the mass in kilograms and acceleration in m/s². All values must be > 0.
Q1: What is a Newton (unit of force)?
A: One Newton is the force needed to accelerate 1 kg of mass at 1 m/s².
Q2: Can this calculate gravitational force?
A: Yes, use 9.81 m/s² (Earth's gravity) as acceleration for weight calculations.
Q3: How is this different from weight?
A: Weight is specifically the force of gravity acting on a mass (W = m × g).
Q4: What if I know force and need to find mass or acceleration?
A: Rearrange the formula: m = F/a or a = F/m.
Q5: Does this work for rotational motion?
A: For rotational systems, torque (τ = I × α) is used instead, where I is moment of inertia and α is angular acceleration.
