Newton's Law of Universal Gravitation:
| From: | To: |
Newton's Law of Universal Gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The calculator uses Newton's Law of Universal Gravitation:
Where:
Explanation: The force between two objects increases with their masses and decreases with the square of the distance between them.
Details: Understanding gravitational forces is crucial for astronomy, space exploration, satellite technology, and understanding fundamental physics principles.
Tips: Enter masses in kilograms and distance in meters. All values must be positive numbers. For astronomical calculations, use scientific notation.
Q1: What is the value of the gravitational constant G?
A: G = 6.67430 × 10⁻¹¹ N·m²/kg². This is a fundamental physical constant.
Q2: Why is the gravitational force so weak compared to other forces?
A: Gravitational force is extremely weak at small scales but dominates at astronomical scales due to its infinite range and always attractive nature.
Q3: Does this equation work for all distances?
A: Newton's law works well for most practical purposes, but for extreme gravity (near black holes) or very precise measurements, Einstein's General Relativity is needed.
Q4: How accurate is this calculator?
A: The calculator uses the standard value of G and provides results with 30 decimal places for precision.
Q5: Can I calculate the force between planets with this?
A: Yes, as long as you input their masses in kg and distance between centers in meters.
