Force Formula:
From: | To: |
Definition: The formula calculates force (in Newtons) using mass and acceleration according to Newton's second law of motion.
Purpose: It helps in physics calculations to determine the force acting on an object when its mass and acceleration are known.
The formula is:
Where:
Explanation: The force acting on an object equals its mass multiplied by its acceleration.
Details: Understanding force is fundamental in physics, engineering, and many practical applications like vehicle safety, structural design, and sports science.
Tips: Enter the mass in kilograms and acceleration in m/s². All values must be positive numbers.
Q1: What is a Newton equivalent to?
A: 1 N = 1 kg·m/s². It's the force needed to accelerate 1 kg mass at 1 m/s².
Q2: How does gravity relate to this formula?
A: On Earth, gravitational acceleration is ~9.81 m/s², so weight (force) = mass × 9.81.
Q3: Can this formula be used for rotational motion?
A: For rotational systems, torque (τ = I × α) is used, where I is moment of inertia and α is angular acceleration.
Q4: What if multiple forces act on an object?
A: The net force is the vector sum of all individual forces (ΣF = m × a).
Q5: How precise should my inputs be?
A: Use appropriate precision for your application - typically 2-3 decimal places for most physics problems.
