![]() This is the same thing as 5 times 10, 5 times 10 times meters per second, times meters per second times seconds, times seconds. ![]() What's neat here is weĬan treat the units, as I've just said, likeĪlgebraic constructs, kind of like variables, so this would be equal to, well, multiplication, it doesn't matter what order we multiply in, so we can change the order. Is equal to our rate, 5 meters per second times our time, times our time, which is 10 seconds. Pretty straightforward way, apply this formula. Were to give you a rate, if they were to say a rate of, let's say, 5 meters per second, and they were to give you a time, a time of 10 seconds, then we can pretty, in a Getting the results in units that actually make sense. What I want to do in this video is use this fairly simpleįormula right over here, this fairly simple equation, to understand that unitsĬan really be viewed as algebraic objects, that you can treat them like variables as we work through aįormula or an equation, which could be really, really helpful to make sure that we're Multiple times in our life that distance can be You are left with the meter on RHS which is the same unit on LHS, this is the basis of DIMENSIONAL (Using Dimensions) ANALYSIS (I don't have to give the meaning do I?) or DAġ hour has 3600 seconds(Ok mind is steady)ġhr(given in question) * 3600 s/1hr (read as 3600seconds per hour, logically that is correct right?) The s in the denominator(speed) and s in the numerator(seconds) cancel out. If you have understood till here then you can try using DA to find 18000m in km. Now calc the numbers and the units of hours cancel out leaving 3600 seconds.ĥ m / s * 3600 s The seconds Unit cancels.You are left with 18000m. ![]() If you are pretty fast your mind will think of converting time to sġ hour has 3600 seconds( Ok mind is steady)ġhr(given in question) * 3600 s/1hr ( read as 3600seconds per hour, logically that is correct right?) You are left with the meter on RHS which is the same unit on LHS, this is the basis of DIMENSIONAL (Using Dimensions) ANALYSIS ( I don't have to give the meaning do I?) or DA ![]() What is the distance I have traveled?Ģ0*20=> 400 (That seems so simple isn't it?) Let's say I am going at 20 m/s speed in 20 seconds. The quantity in the bracket is their unit ![]() Although they do not specifically mention Graphical Analysis Pro, these experiments offer excellent opportunities to incorporate the app into your teaching.There is nothing much to worry We know distance = Speed * Time On August 1, we will be offering a free webinar that highlights ways to use the app’s advanced features with some of our most popular Go Direct physics sensors to explore force, motion, and sound.Īhead of the webinar, I’m sharing three experiments that are great for hands-on physics learning. The app works on a wide variety of devices and platforms, including Chromebooks™, cell phones, and iOS. Graphical Analysis Pro also promotes accessibility, which is great for educators and students alike. For example, I would have loved to have been able to do live data sharing and use FFTs with my students. Some of the app’s features were inspired by my experience as a high school physics teacher. Energy, acceleration, and simple harmonic motion are just a few important physics principles for students to learn-and using the Graphical Analysis Pro app with our Go Direct ® sensors can help bring these abstract scientific concepts to life. ![]()
