# Video on Newton’s second law of motion

Hi and welcome to my video on Newton’s second law of motion. The second law is one of three laws published by Sir Isaac Newton in 1687.

I start the video by introducing the law in the form F=ma and explaining each term in the equation and how we may use it to predict forces and accelerations of objects. I then conduct three experiments using different forces to accelerate wooden blocks along a frictionless surface. By observing the positions of the blocks at one second intervals I’m able to demonstrate the way in which force and mass affect the acceleration of an object.

You can follow me as I use my tablet to work through examples of the use of the equation F=ma to predict the accelerations and forces acting on the blocks.

The video is available in high definition. Once you start playing the video you can use the options at the bottom right of the video player to select a higher resolution format and to play it full screen.

You can also read my tutorial on the second law here where I provide further explanation of the second law.

I have now released an ebook which explains Newton’s second law of motion in five easy to understand steps. It is available in two versions; one for the iPhone and iPod touch and one for the iPad. The ebook contains over eleven minutes of animation, a range of images, and questions with solutions so that you may check your understanding. If you are interested in obtaining a copy, please follow the links below to the iBookstore where you may download a free sample or buy the full ebook. You can also see a video of the contents of the ebook here.

Thanks

Thanks for your feedback

Hi,

Thanks for your feedback Janna. Mac

you explain the best

Plz launch your Android app So that android buddies may also enjoy your videos…

Thankz

Hi Bilal, Unfortunately Google doesn’t provide an option for me to supply books with embedded video at present but I will do this as soon as the option is available. Mac

HI sir

YOUR explanation is the best

I am not just understand but I love it too

Please explain to me the friction force

THanks a lot

Hi Lamia, thanks for your feedback. I haven’t made a video on friction force yet but it is on my list of possible topics for a future video. Have a look on YouTube at some of the other great educators there and see if you can find an explanation of friction force.

Prof, Can I learn physics in one month?

Thanks

Ray

Hi Ray, you can learn a lot in one month. You should set a realistic scope for the amount you wish to learn. Physics is a very broad subject and so you can spend many years studying it.

This is very cool……

Hope to see more!!!

Well done! This is so helpful…

Thanks for the feedback Ryo.

Cool animation , examples and explanation.It helped me for my exams>please do put more videos on physics

Thanks Aadil, I am working on my video on Newton’s third law of motion now.

Regards Mac

This is very useful. Thank you very much prof Mac

🙂

Thanks for your feedback Deven. Mac

thnx for the vid thnx u verry much!!!

Thanks for your comment John.

Mac

professor that was cool .you are incredible.i am glad that i found ur vid 2 weeks before exam

regards

dev

Thanks Dev. Good luck in your exams. Mac

Hi Prof Mac,

Your videos are incredible. I wish Zambian science teachers/lecturers would present learning material that way.

Thanks Moses. Mac

wow wt a grat explanation……….

Thanks for your feedback Puneet. Mac

omg…! tat was excellent explanation..! thanks mate 🙂 🙂 keep on continuing the gud job ! MAC

Thanks for your feedback Balu.

Mac

hi prof. mac

I am very glad to join your website.

uctually nowadays I am very interesting to watch your vedio lessons about newtons laws of motion and I understood alot of experience and willy appreciate that your unforgettible work and I hope I’ll be a professor like you.

thank you very much.

Hi Yahya,

Thank you for your feedback. Best wishes for your future studies.

Regards Mac

cool cool explaination.
