Force Formula:
From: | To: |
Definition: This calculator computes the gravitational force acting on an object using Newton's second law of motion.
Purpose: It helps students, engineers, and physicists determine the force exerted on an object due to gravity.
The calculator uses the formula:
Where:
Explanation: The mass of an object is multiplied by the gravitational acceleration to determine the force exerted on it.
Details: Understanding gravitational force is fundamental in physics, engineering, and various applications from construction to aerospace.
Tips: Enter the mass in kilograms and gravitational acceleration (default 9.81 m/s² for Earth). All values must be > 0.
Q1: What is standard gravity on Earth?
A: Approximately 9.81 m/s², though it varies slightly by location (9.78-9.83 m/s²).
Q2: How would this change on other planets?
A: Use different g values (Moon: 1.62 m/s², Mars: 3.71 m/s², Jupiter: 24.79 m/s²).
Q3: What's the difference between mass and weight?
A: Mass is constant (kg), while weight is the force (N) which depends on gravity.
Q4: Why is the result in Newtons?
A: Newton is the SI unit of force (1 N = 1 kg·m/s²).
Q5: How can I convert Newtons to pounds-force?
A: Multiply by 0.224809 (1 N ≈ 0.225 lbf).
