Tides -- Newton's 3rd Law Resource

WHO LIKES THE BEACH? I PREFER THE LAKE, BUT IT'S MY OPINION.

So I'm sure many of you have used this video as a resource. Well, while we're talking about tides, let's mention some of the good stuff.

First off: "Everything with mass attracts all others things that have mass."

What we know is that the Force of gravity is inversely proportional to the distance between the objects. As they get further apart, the force is less, as the distance decreases, the force increases.

Tides - definition: Tides are caused because of the difference in force felt by opposite sides of the Earth.

There are 2 high tides and 2 low tides a day (every 24 hours). Each is 6 hours apart.

• Spring tides are when the sun, Earth, and moon line up. The highest and lowest tides (more/less than usual) occur. *Full & new moon*
• Neap ties are just after the first or third quarters of the moon occur. *Such as a gibbous moon or crescent*

He draws the forces acting on the moon with arrows, which helps! At 0:18 seconds, he draws both sides of the pull. Newton's 3rd Law proves that "the close side of the Earth gets pulled away from the middle, which in turn gets pulled away form the far side."

Gravity is weaker at a greater distance, and in the video, he draws a hose and sheep. I like this image a lot!

His last [proposal/theory/awesomeness] is that by the year 270000000000, "a day and a lunar month will each have the same length: about 50 of our current days."

TALK ABOUT A LONG DAY.

CHEERS.
