🎈Everything is moving
Everything in the Universe is moving all the time. Even you now, while sitting and reading here, are not in the absolute quiescence. Can you believe in it?
Why is that?
Everything is made up of atoms, and atoms move constantly because their electrons are never at rest and are constantly moving in their electronic layers.
Planet Earth is also never at rest. Earth rotates quite rapidly around its axis, and at the same time moves around (orbits) the Sun at a very high speed.
Do you know the astronaut in the spaceship, orbiting the Earth. If they start looking through binoculars, at an object outside the spaceship, they will often need to adjust the focus for the binoculars to see well. Why? Because they are in the spaceship and because of that are moving at a very high speed while the spaceship are orbiting.
That’s why everything is always in motion, and depending on the starting point of observation, the speed of movement can be different at one and the same time.
Why do objects move at a certain speed? What makes them move this way? When do they stop moving and when? What makes them stop and what happens next?
The basic concepts that explain the movement are described by Isaac Newton a long time ago.
He manages to describe the basic principles of movement in 3 laws of motion:
👉 Newton’s first law – see what it says.
👉 Newton’s second law – reed more.
👉 Newton’s third law – see what it says.
