Professor Mac Explains Newton's First Law of Motion

In this episode, Professor Mac explains Newton's first law of motion. This is one of three laws published by Sir Isaac Newton in 1687.

The laws explain the interaction of forces and objects and the way in which the motion of an object is affected by force. This knowledge enables scientists and engineers to design and develop the products we use everyday.

I hope you enjoy the video. Let me know your thoughts on how effective you find the approach of using animation to explain this type of topic.

Hi All. Once the third video of the Newton's Laws of Motion series is finished I will be producing a Question and Answer video. This will feature the best of the questions raised by the YouTube community on Newton's Laws of Motion. If your question is used in the video I will acknowledge you in the video using your YouTube username. So this is your opportunity to appear in one of Professor Mac's videos. Ask your questions here and subscribe to be notified when the video is released. Mac

Great video, but does that mean that it will continue no matter what in eternity unless it's held back by any forces? If you are in a room where you have for instance a table like in the clip, with no resistance so that the horisontal force only gets that first kick from the left making the horisontal balance unstable, the object will continue forever?

[learnwithmac]

@Mential Hi Mential, Yes you are correct. Once the object starts moving along the table, and assuming that the table does not resist the motion, then the object will continue moving in a straight line forever. Never slowing down or speeding up, just moving with constant velocity for eternity. Amazing isn't it!. In everyday life we never see this since there are always resistance forces acting such as friction. Regards Mac

@learnwithmac However, that's also assuming that there is no air resistance either; a gas or oxygen free environment, such as outer space.

[learnwithmac]

@evilslig Yes that's right. The sum of forces must be zero in the direction of motion for it to keep moving. See my movie on the second law which explores this a little further. Thanks for commenting. Mac

tnx alot

@learnwithmac nigga step ya game up i wanna learn physics n shit what am i gonna do with only two vids dawg

[seekertosecrets]

Very interesting.
