Force Due To Gravity Formula:
From: | To: |
Definition: This formula calculates the gravitational force acting on an object based on its mass and the acceleration due to gravity.
Purpose: It helps in physics calculations, engineering designs, and understanding the weight of objects in different gravitational fields.
The formula is:
Where:
Explanation: The force exerted by gravity on an object is directly proportional to its mass and the local gravitational acceleration.
Details: Understanding gravitational force is crucial for structural engineering, space exploration, and any application where weight affects design or performance.
Tips: Enter the mass in kilograms and gravitational acceleration (Earth default is 9.81 m/s²). All values must be > 0.
Q1: What's the standard value of g on Earth?
A: Approximately 9.81 m/s², though it varies slightly by location (9.78 at equator to 9.83 at poles).
Q2: How does this relate to weight?
A: Weight is simply the force due to gravity, so this calculation gives an object's weight in Newtons.
Q3: What would g be on other planets?
A: For example: Moon (1.62), Mars (3.71), Jupiter (24.79) m/s². Use these values to calculate weight elsewhere.
Q4: Why is the result in Newtons?
A: Newton is the SI unit of force (kg·m/s²), named after Isaac Newton who formulated the laws of motion and gravity.
Q5: How do I convert Newtons to pounds?
A: Multiply by 0.224809 to get pounds-force (lbf). 1 N ≈ 0.225 lbf.
