Okay, good for you. Let's go in our classroom. Any minute our class will start now.
Oh no! Are you okay Tina? How did it happened?
Okay! I think Mrs. Perch is now on her way. Let's go!
It kinda hurt my head but I'm still fine Bea. Maybe it's just a strong wind.
Good day everyone! I hope you're doing good. So let's start our discussion for today. And it's about the Law of Gravitation. Did you know that there's a popular story behind the Universal Law of Gravitation? Well, Isaac Newton was just seated under an apple tree, suddenly an apple dropped on his head, and instantly he realized about the Universal Law of Gravitation.
Newton realized that the force that triggered the apple's acceleration (gravity) had to rely on the weight of the apple. And because the force acting to pull down the apple's acceleration also triggers upward acceleration of the earth (Newton's third law), this force must also depend on the mass of the earth. Thus, for Newton, the force of gravity acting between the planet and every other object is directly proportional to the mass of the earth, partially proportional to the mass of the object, and inversely proportional to the square of the distance between the centers of the Earth and the object.
Newton's absolutely brilliant insight: once the force of gravity hits the top of the tallest tree, it does not go any further. In fact, it may not extend all the way to the moon's orbit. And, the Earth's orbit of the Moon may be an effect of the gravitational force, since the gravitational force could change the speed of the Moon in such a manner that it matched an orbit around the Earth.
Gravity is very important to humans and to our planet. Without it, we will not survive on Earth. The gravity of the sun keeps Earth in orbit around it, keeping us at a safe distance to enjoy the sun's warmth and energy. It's holding back our atmosphere and the oxygen we need to breathe. Gravity is what keeps our world together. That's all for today everyone I hope you understand it very well. Class dismissed.
Well I guess that explains. I'm now more interested about gravity!! Gravity really performs a significant role in the growth of life because it prevents everything from flying away on Earth.
Woah it seems like it's similar on what happened to you earlier. In your case it's an orange while Isaac Newton's was an apple. Anyways back in our lesson, we wouldn't have an atmosphere without gravity. Because it is the force that pull things back to Earth.
