Force Formula:
From: | To: |
Definition: This calculator computes the force exerted when a mass is accelerated, according to Newton's Second Law of Motion.
Purpose: It helps physics students, engineers, and scientists calculate force in newtons based on mass and acceleration.
The calculator uses the formula:
Where:
Explanation: The mass is multiplied by the acceleration to determine the resultant force.
Details: Understanding force calculations is fundamental in physics, engineering, and many practical applications like vehicle dynamics, structural design, and space exploration.
Tips: Enter the mass in kilograms and acceleration in m/s² (default 9.81 m/s² for Earth's gravity). All values must be > 0.
Q1: What is a Newton?
A: A Newton is the SI unit of force, defined as the force needed to accelerate 1 kg of mass at 1 m/s².
Q2: Why is Earth's gravity 9.81 m/s²?
A: This is the average acceleration due to gravity at Earth's surface, varying slightly by location.
Q3: Can I calculate weight with this?
A: Yes, weight is the force of gravity on an object. Use mass × 9.81 m/s² for Earth's gravity.
Q4: What if I have pounds instead of kg?
A: First convert pounds to kg (1 lb ≈ 0.453592 kg) before using this calculator.
Q5: How is this different from F=ma in other units?
A: The formula works the same, but unit conversion is needed for non-SI units (pounds, feet/s², etc.).
