Isaac Newton's celebrated falling apple is cited to explain the force of gravity and the unit with which the force of gravity is measured. Concept: Force of gravity = mass x 10m/s2

  • Inspiredbythefire123@ actually curvatures in spaceTime are the result of gravity, if the apple were placed in space completely still within gravity's limits it would be pulled in a straight path to earth, if u were in space and tried to throw the apple past the earth with enough force it would go into orbit around the spaceTime curvature caused by the earths gravity, understand what I'm saying?

  • so 1 Newton=100gx10m/s*s

    then 2 Newtons must be 200gx10m/s*s? Or am I confused?

  • thank this really helped me in my science test

  • That isn't how gravity works.. Gravity is a product of the curvature in spacetime

  • damn i needed these vids when I was doing physics... i'd have gotten a better foundation to build on... my physics teacher was the worst! (eventually got fired for sexually harrassing a female student).

  • @MarkProffitt Oh, hi. Funny, didn't get this in my email... I guess I tend to think of myself holding something up as applying a force, because I'm expending energy, I'm applying myself, as 'twere. But, I suppose it's like the idea of equal and opposite reactions. I can push on a wall, and the wall can be said to be pushing back...

  • @ion010101 Just try holding something up. Gravity is pulling it towards Earth. If you stop exerting the force to hold it up it falls. The more massive the more force needed.

  • I'm a little unclear as to how "the stem" is "a force" holding the apple up...

  • way to round 9.81 m/s2 up to 10...

  • My teacher made us watch these in middle school. They're very entertaining :)
