Defining Gravity: Crash Course Kids #4.1

Defining Gravity: Crash Course Kids #4.1

(Intro Music) If I told you that you just won the lottery, what would you do? If you’re like me, you’d jump up and down and scream. And after you are done freaking out and jumping in the air, you’d *landing sound* land on your feet, right? But WHY would you land back on the ground instead of just floating off into space? *music* It’s because of a little something we call gravity. Gravity is what pulls everything toward the ground. Including you! Without the force of gravity, there would be no life on Earth. Air, water, animals? Everything would fly off into space. There’d be no you, no me, no french fries; nada. Think of gravity like the invisible superglue that holds our massive world together. You can’t SEE it, but it’s always there. An English scientist, named Isaac Newton, was the first person to seriously study
gravity (over 300 years ago). There’s a famous story about him that
you might have heard. Supposedly, Sir Issac was hanging out underneath an apple tree thinking, -PROBABLY partly napping- when an apple fell from the tree
and conked him on the head. That’s when Sir Issac had an “aha moment”. Why did the apple fall down to the ground, and not up, or sideways? He realized that a special kind of force, which we now know as gravity, was acting on all of the objects on earth; pulling them toward it. Once the apple became too heavy for its stem to hold it anymore, the gravitational pull of Earth brought
the apple down on to Newton’s noggin. Newton also realized it doesn’t matter
how heavy an object is either. Whether you’re holding an apple, or a
bowling ball, or a feather… if you let go of it, that sucker’s going
down. We’re gonna make a whole video about this later. Basically he determined
that what goes up must come down. Sir Isaac was a pretty smart dude. Okay, so you know that if you jump up, you’ll eventually land back on the ground and you know that an apple drop-down will land on the ground too, (Music Playing) To see how gravity will act, pick up the
tennis ball or any small, round object and hold it in your hand. Let’s toss it in the air and watch it
fall to the ground. No surprise here, okay now pick it up and
hold it over your head. Let go and watch it fall once more. Again, not a shocker. Now throw it to your left. Ball down. Pitch it to the right and watch it go down again. No matter where you throw the
ball, it’s going down. So, we’ve determined that near the
surface of the earth (where we all are), gravity is the cause that produces the
effect of all unsupported objects falling down. The ball will go up or to
the left or to the right for a little bit, but eventually it’s going to be
pulled back down to the ground, no matter what. Gravity’s got a hold on… well, everything. [theme music]

  2. total bs. If something is heavier than air it sinks/falls, if not, it rises, floats. Just the same as in water. Oxygen is water, just less dense.

  3. I go to school and the teacher put this and all the class goes YAAAAAAAAAAAAAAAAAA because we love the channel ๐Ÿ˜›

  4. Explanation of all downward falling motion !

    If GAS BONDING is a fact , gravity is not !

    All downward falling motion including Newton's apple begins when rising gas molecules becomes trapped gas molecules , known as gas bonding , which takes on a state of solid mass , blocking out it's electrons motion , it's fire power , thus becomes energy lock lifeless gas molecules , and falls downward in real time , fallowing it's electrons unlimited potential velocity at the speed of light , connecting with the earth energy conservation system , establishing a downward falling path for trapped lifeless gas molecules / solid objects only .

    Equating the above fact with the physical universe same as Einstein e = mc2 equates with the physical universe .

    E = Energy = MM = Molecule Motion = Molecules in motion within star flames earth gases birds and balloons plains and rockets , even us humans rise from molecules in motion creating an energy flow , the ruling force of the universe .

    M = Mass = GB = Gas Bonding = Gas Bonding takes on a state of solid mass .

    C2 = Light Speed = E = Electrons = Electrons unlimited potential velocity at the speed of light connects with the earth energy conservation system establishing a downward falling path for trapped lifeless gas molecules / solid objects only .

    Note ! All gas rise upward into the atmosphere from molecules in motion fired up by its electrons creating an energy flow .

  5. Ok kids ask your science teachers or professors to recreate earth in a weightless environment with water & objects sticking to it while it spins @ 10s of thousands of mph while also moving in one direction @ 10s of thousands of mph. You ever ride a gravitron @ a fair?

  6. Fake definition to make/create mathematical formula for the non existent gravity. Every thing falls down if it is not supported by some thing or if it is not controlled.
    Planes don't fall because they are controlled. Birds don't fall because they control themselves. a tiny sand falls down because it does not control itself…. Gravity does not exist.

  7. You are amazing please I need you to provide a video on the human digestive system and human respiratory system
    please help me

  8. question…. why didn't Newton notice other things falling? Not to upset anyone but even as a kid this story always bothered me. A scientist who knows alot…..even physics…. doesn't notice things that fall? Think…. this is the key to this story.

  9. Might be worth taking a look at it's being looked at as the first true Unified Field Theory

  10. But when the aeroplane that is in the air do not come down by it self ,it comes down when the pilot forces it down right?

  11. She lied to me. any way you through it the object will come down, but what if I through it into space from earth. will it come down? watched this in class and had to say it. I promised my friend that I would. lol

  13. Frank DiMeglio defeats Newton and Einstein and truly balances and unifies physics/physical experience:

    ELECTROMAGNETISM/ENERGY IS GRAVITY. This is proven by F=ma AND E=mc2. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE.


    Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ACCORDINGLY, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent WITH/AS F=ma, E=mc2, AND what is perpetual motion; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT.

  14. What percentage of the universe may be gravity. Assuming 95% of universe is gravity could the known 5% of matter be the force creating the 95% gravity. Does the 5% draw in the gravity from the 95% and condense it. Braking systems.

  15. There is no force pulling anything, gravity is a word and that is all it is. The idea of the globe came about and they dreamed up the magical force to explain to people why we do not fall of the ball. Its complete crap there is no such thing as gravity and no evidence anywhere that we live on a ball kids. welcome to reality, what is earth?? the answer is…. we do not know, maybe some do but they ain't telling us.

  16. Stop brainwashing children with concepts and abstractions. Showing them plastic toys and repeating the gibberish you, yourself have assumed and believed to be beyond reproach is emotional abuse of a child's impressionable mind.

    Offer them a practical example of a body of water naturally conforming to the exterior of shapes. Oh wait…….insert honesty here…….

    Offer them a practical example of a gas pressure being created and maintained without physical containment, you know, some actual tangible proof using the very substances you profess to know and understand, instead of browbeating and intimidating innocent children into sumbitting to your cult beliefs.

  17. I thought gravity is so much more complicated >:/ AND IT IS GOD DAMMIT, U CANT CHANGE MY MIND! REEEEEEEEEEEEEEEE >:000
