Law of Gravitation
Storyboard Text
- Hi! Can I asked you a questions?
- Sure!
- Its about the Law of gravitation. What is the contribution of gravity?
- The force of attraction between you and the Earth is your weight. Gravity determines the "escape speed" for an object like a rocket. The stronger the gravitational pull of the object, the larger the escape speed.
- Nice, another question is, what is the importance of law of gravitation?
- The importance of universal law of gravitation is that it explains the motion of planets around the sun; the motion of moon around the earth; and the motion of artificial satellites around the earth.
- Ahm, some more?
- And it also explains the phenomena of rainfall, snowball, and flow of water in rivers on the earth.
- Alright, and my next question is, who is the proponent of the universal law of gravitation?
- Isaac Newton put forward the law in 1687 and used it to explain the observed motions of the planets and their moons, which had been reduced to mathematical form by Johannes Kepler early in the 17th century.
- Thank you for all your responds!
- Nice, some more for contribution of law of gravitation?
- It encapsulates the idea that all the particles of matter in the universe attract each other through the force of gravity - Newton's law tells us how strong that attraction is.
- you're welcome. Bye!
