What are some products that were developed directly from advances in electromagnetism, solid-state physics, and nuclear physics?
Television, computers, domestic appliances, and nuclear weapons
Where does the word 'physics' come from?
The word 'physics' comes from the Latin 'physica' ('study of nature'), which is a borrowing of the Greek 'φυσική' (phusikḗ 'natural science')
What is the meaning of the Greek term 'φύσις' (phúsis)?
The Greek term 'φύσις' (phúsis) means 'origin, nature, property'
Which ancient civilizations were involved in early astronomy?

- What is the Universal Gravitation Equation according to Newton's Law of Universal Gravitation?
The Universal Gravitation Equation, according to Newton's Law of Universal Gravitation, is given by $F = G\frac{m_1m_2}{r^2}$, where $F$ is the gravitational force between bodies, $m_1$ and $m_2$ are the masses of the bodies, $r$ is the distance between the centres of two bodies, and $G$ is the universal gravitational constant.
- What is the value of the universal gravitational constant (G)?
The value of the universal gravitational constant (G) is $6.673 \times 10^{-11} N m^2/kg^2$.
- Who experimentally determined the precise value of the universal gravitational constant (G)?
Henry Cavendish experimentally determined the precise value of the universal gravitational constant (G).
- What does the Universal Gravitational Law explain?
The Universal Gravitational Law can explain almost anything, right from how an apple falls from a tree to why the moon revolves around the earth.
- What does Newton's Law of Universal Gravitation state?
Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with force directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
