# 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.

Thanks prf mac,even we students from tanzania we enjoyed your lessons

• The Professor says:

I’m pleased you enjoyed my videos August. Regards Mac

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 for your feedback Cravenal. 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.

This is a good and interesting and understant
ding teaching.I would like to get the other tow class.That is the class about Newtons Law.
Thanks alot.
