Question

State Newton’s universal law of gravitation.

Answer 1

Step 1: Understanding Newton’s law of gravitation
- According to Newton’s universal law of gravitation, the gravitational force (\( F \)) between two objects of masses \( m_1 \) and \( m_2 \) separated by a distance \( d \) is given by: \[ F = G \frac{m_1 m_2}{d^2} \] where \( G \) is the universal gravitational constant. - This law explains that: - The force increases with increasing mass (\( m_1 \) and \( m_2 \)). - The force decreases as the distance (\( d \)) between the masses increases. Thus, every object in the universe exerts a gravitational force on every other object.
