Video on Newton’s second law of motionAugust 21, 2011 22 Comments
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.
