[ MUSIC ]>>WELCOME TO THE INTERNATIONAL SPACE STATION. I’M NASA ASTRONAUT MARK VANDE HEI. TODAY, WE’RE GOING TO TALK ABOUT NEWTON’S THIRD LAW. HOW DO YOU THINK IT WILL HOLD UP IN MICROGRAVITY?>>FOR EVERY ACTION, THERE IS AN EQUAL AND OPPOSITE REACTION. THIS MEANS THAT IN EVERY INTERACTION BETWEEN TWO OBJECTS, THERE ARE A PAIR OF OPPOSITE FORCES ACTING ON EACH OBJECT AT THE SAME TIME– A FORCE PAIR. YOU CAN SEE THAT THERE ARE MANY EXAMPLES ON EARTH. [ MUSIC ] IN SPACE, THRUSTERS EXPEL ONE WAY AND THE VEHICLE IS STEERED IN THE OPPOSITE WAY.>>HELLO AGAIN. MORE BASKETBALL STUNTS THAT I CAN’T DO ON THE GROUND– AT LEAST NOT WHILE GETTING THIS MUCH HANG TIME. ALL RIGHT, BACK TO SERIOUS BUSINESS. I’VE GOT A BASKETBALL RIGHT HERE. IT’S GOING TO BE OBJECT 1. I’M THE SECOND OBJECT. IF OBJECT 2– MYSELF– APPLIES A FORCE TO OBJECT 1, THEN THAT SAME FORCE WILL BE APPLIED, ACCORDING TO NEWTON’S THIRD LAW, BY OBJECT 1 ONTO OBJECT 2. HOWEVER, THERE’S A BIG DISPARITY IN THE MASS. OBJECT 1 IS A VERY LIGHT MASS OBJECT. OBJECT 2, MYSELF, IS A LARGER MASS OBJECT. SO I’M GOING TO TRY AND MAKE MYSELF ABOUT THE SAME SHAPE AS THIS BALL– SEE HOW THAT WORKS FOR US. AND I’M GOING TO APPLY THAT FORCE. YOU SAW THAT FORCE APPLIED TO THE BALL MADE IT ACCELERATE QUITE A BIT. IT REALLY DIDN’T ACCELERATE ME MUCH AT ALL. NEWTON’S THIRD LAW AGAIN, BUT THIS TIME WE’RE GOING TO USE TWO SIMILARLY MASSED OBJECTS. JOE AND I HAVE ABOUT THE SAME MASS. SO JOE, GET INTO A BALL. I’LL DO THE SAME. I’M GOING TO FACE YOU THIS WAY SO I DON’T THROW YOU INTO SOMETHING YOU CAN’T SEE.>>ALL RIGHT.>>NOW I’M GOING TO GET INTO A BALL BEHIND JOE AND I’M GOING TO APPLY A FORCE TO HIM. NOTICE THAT WHEN I APPLY THE FORCE TO JOE, IT ACCELERATED JOE AWAY FROM ME, BUT I GOT ACCELERATED AWAY FROM HIM AS WELL, BECAUSE THE FORCE APPLIED TO JOE ENDED UP BEING THE SAME FORCE THAT WAS APPLIED TO ME. NOW YOU’VE SEEN NEWTON’S THIRD LAW IN SPACE. NOW TEST IT OUT ON EARTH. SEE YOU NEXT TIME! [ MUSIC ]

    amazing video

    I so appreciate that you're taking the time to demonstrate the laws of motion in such a visually intuitive way, my son will love it. A pity there's no way to demonstrate F = G M1 M2 / r^2 – or if there is I can't think of it. Maybe you could show Galileo's Principle of Relativity. It's the basis of the laws of motion after all.

    This is awesome

    In before flattards and space deniers try to tell us it's filmed in a pool or in the vomit comet. I think they're just too scared to admit that we can achieve such amazing things because they're too dim to understand how it all works, so they want to criticise it and bring other dim people into their circle. Flattards and space deniers really embarrass us as a species and take us back hundreds of years. Great job, NASA, keep on being awesome!

    Impressive demonstration. Let me please add a comment:
    Newton's third law only applies when Mark Vande Hei applies a force against a body or object that does not move for example the a wall of the space station, then F(wall)=-F(Mark). However when Mark pushes the basketball F(ball)<<-F(Mark), or when Mark pushes Joe, F(Joe)<-F(Mark), otherwise if F(Joe)=-F(Mark) no one moves. When one of the object moves, then the third law no longer applies since F(object)<-F(Mark) and we must use Newton's second law that describes how the object will move under the force applied by Mark. F(Mark)=m(object)xa(object).
    If Mark makes himself the shape of a ball and keeps quiet, then we must use Newton's first law, with reference to the space station walls. Hence we could say that Newton's three laws of motion could be simplified to a single law with three cases, which are more intuitive. Can you please formulate this law?

    If you think rockets can work in space, then you do not understand Newton’s 3rd law at all…

    this is stupid

    do you have newton 3rd law applied in vacuum ??

    thx

    “So let me get this straight Sir… the man from space… told you to push this man to see if you would accelerate backwards…”

    – YES! FINALLY THIS GUY GETS IT!

    WHY AND HOW DREAM EXPERIENCE AND PHILOSOPHY ULTIMATELY MADE THE TRUE UNIFICATION OF PHYSICS/PHYSICAL EXPERIENCE POSSIBLE:

    Consider what is THE SUN, and then consider what is THE PHOTON (c, A POINT). THINK about F=ma AND E=mc2. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND ACTUAL IN BALANCE. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It is a very great truth/fact that the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. THINK about it. THOUGHTS ARE INVISIBLE.

    Now, very THOROUGHLY consider what is THE EARTH. It is ALSO a very great truth/fact that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. THE EYE IS THE BODY. The BALANCE of being AND EXPERIENCE is ESSENTIAL. (BALANCE AND completeness go hand in hand.) THINK about it.

    Very carefully consider what is THE EYE. Notice the black space of THE EYE, AND notice that THE DOME of a person's EYE is ALSO VISIBLE. MAGNIFICENT. The stars AND PLANETS are POINTS in the night sky. NOW, we OVERLAY what is THE EYE in RELATION to what is THE EARTH. (Very importantly, outer "space" involves full inertia; AND it is FULLY INVISIBLE AND black.) SO, we now consider the semi-spherical, translucent, AND QUANTUM GRAVITATIONAL DOME that is the BLUE SKY. (It is a BALANCED reflection, as defined.) We can LOOK at what is then THE BLUE EARTH. It ALL makes perfect sense. Points are POINTS. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Great.

    The ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED FROM F=ma. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/AS what is BALANCED ELECTROMAGNETIC/GRAVITATIONAL FORCE/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY.

    Dream experience is possible/potential AND ACTUAL IN BALANCE. There is no outsmarting the GENIUS OF DREAMS. Now, dream experience is/involves true/real QUANTUM GRAVITY; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Dream experience GROWS/INCREASES. Dreams BALANCE being AND EXPERIENCE. THE EYE is ALSO THE BODY. MOST IMPORTANTLY, in dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. INDEED, BALANCE AND COMPLETENESS go hand in hand. ELECTROMAGNETISM/ENERGY IS GRAVITY. IT IS DEFINITIVELY AND CLEARLY PROVEN. It ALL makes perfect sense. SO, the INTEGRATED EXTENSIVENESS of thought (AND description) IS improved in the TRULY SUPERIOR mind. Absolutely ingenious !!!!!!! Dreams make thought MORE LIKE sensory experience in general, thereby IMPROVING upon memory AND UNDERSTANDING !!! Learn to think for yourselves.

    Very carefully consider the man who is standing on the EARTH/GROUND. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Piece it ALL together. Fantastic !!!! So, THE EYE is, in fact, a BALANCED WHOLE in RELATION to (AND WITH) the SPACE around it. THE EYE is ALSO the body. The BALANCE of being AND EXPERIENCE is ESSENTIAL. BALANCE AND COMPLETENESS go hand in hand. We can see that these spaces are, in fact, proportionately advanced IN BALANCE.

    SO, it is now time to turn to the DIRECT AND FULL COMPARISON of what is THE SETTING MOON AND THE ORANGE SUN. The fully illuminated AND setting MOON MATCHES the brightness of the SETTING AND ORANGE SUN. MOREOVER, the curvature or shape of this Moon MATCHES that of the EARTH/ground. Also, this Moon AND Sun are the SAME SIZE as what is THE EYE (of necessity). Notice that these manifestations or forms occur at EYE LEVEL/BODY HEIGHT. Therefore, these are QUANTUM GRAVITATIONAL incarnations or forms that must be identical (on BALANCE) to what is the EARTH/GROUND AND LAVA. The COMPOSITION of lunar rocks IS practically IDENTICAL to that of Earth rocks. SO, the FLAT, SETTING, AND ORANGE SUN (with the SPACE around it THEN going invisible AND VISIBLE IN BALANCE) is a BALANCED, QUANTUM GRAVITATIONAL, AND BODILY/VISUAL EXPERIENCE in RELATION to what is THE EYE, THE EARTH/GROUND, AND LAVA. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The Moon may also be blue.

    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. It ALL makes perfect sense. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ACCORDINGLY, the rotation of the Moon MATCHES it's revolution. It is PROVEN. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL FORCE/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. IT ALL MAKES PERFECT SENSE. THIS IS THE TRUE AND THE CLEAR UNIFICATION AND BALANCING OF PHYSICS/PHYSICAL EXPERIENCE. BALANCE AND COMPLETENESS go hand in hand. Really THINK about it ALL. GREAT !!!!
