An eclipse of the moon. You can see the curved shadow of the Earth. Once people have seen that something happens through observation, sooner or later it will occur to them to ask why it happens. And is there any way to prove that it will happen the same way every time? Sumerians developed advanced math to [...]

What is inertia? Physics – Science

By |2018-05-31T11:49:29-07:00August 18th, 2017|Physics|

The bus is heavy, so it's hard to get it moving. A law of physics first suggested by the Uzbek scientist Ibn Sina about 1000 AD states that "an object at rest tends to remain at rest, and an object in motion tends to remain in motion." Scientists call these tendencies inertia. Inertia is a way of measuring [...]

Isaac Newton, mathematician and physicist About 1000 AD, in the Islamic Empire, Ibn Sina came up with the idea that an object moving in a vacuum would just keep moving forever without slowing down. But to prove this was always true, you'd need calculus, which hadn't been invented yet. In the 1700s, Isaac Newton figured out [...]

Light takes years to reach us from these stars far away in space. When solid objects move through space, they follow certain rules that let us predict how they will act. We call the first three rules Newton's Laws of Motion, and they say that: An object in motion tends to remain in motion, and an [...]
