Newton's Gravity Force

Experiment Module

Gravity Force

Theory & Logic

Theoretical Background

Physics describes the fundamental mechanism of the universe. The Newton's Gravity Force is an essential tool for understanding Newton's Gravity Force in quantitative terms. Calculate Fg = (G*m1*m2)/r².

Mathematical Formulation

The relationship between the variables is governed by the following equation:

Result = (6.674e-11 × m1 × m2) ÷ (r × r)
Eq 1.1: Governing Formula

Variable Legend

Symbol Parameter Unit
m1 Mass 1 kg
m2 Mass 2 kg
r Distance m

Practical Calculation Example

Problem

Calculating the result when:

  • Mass 1 = 20 kg
  • Mass 2 = 15 kg
  • Distance = 60 m

Solution

Substituting into Eq 1.1:

Result = (6.674e-11 × 20 × 15) ÷ (60 × 60)
