Newton’s universal law of gravitation — task. Science TNSB Mentoring, Class 10.

Answer all the questions:

State the universal law of gravitation and deduce its mathematical expression.

1. Newton’s universal law of gravitation:

This law states that,

The force between the particles is always , and it where they are placed.

Let \(m_1\) and \(m_2\) be the masses of two bodies \(A\) and \(B\), placed \(r\ metre\) apart in space.

\begin{array}{l} F α i_{i} \times i_{i} \\ F α \frac{i}{i^{i}} \end{array}

On combining the above two expressions,

\begin{array}{l} F α \frac{i_{i} \times i_{i}}{i^{i}} \\ F = \frac{{i \times i}_{i} \times i_{i}}{i^{i}} \end{array}

2. The universal gravitational constant (G) remains the same .
