Professor Mac explains Newton’s first law of motion

This is my video where Professor Mac explains Newton’s first law of motion. It is the first in a series of episodes exploring Newton’s three laws of motion.

The solution to the question posed in the video regarding what would happen if the block was moving on a surface which provided resistance to the motion may be found here.



I teach physics and engineering through animation.

    Thank you professor Mac
    I just wonder why is the box counting the motion?
    It should stop because no forces is longer acting on it.
    And what is the resistance is doing there?

    • The Professor says:

      Hi Abdallah, The box continues its motion on the table because there is no friction in my virtual laboratory. In reality all surfaces have friction and the block would slow down. I have modelled a frictionless surface in order to demonstrate what would happen if there was no friction. Regards Mac

    Thank you mac for a wonderful video on newtons first law of motion,
    It’s very informative
    Thank you mac

  6. this is creepy! but it made sense.

  7. The Professor says:

    Thanks. The video on the second law is in the final stages of completion. It will be released in the near future.
