Physics is a subject that is easy for some students and hard for others. For some, it can seem almost impossible to grasp. Good tutoring can make all the difference. I can imagine most of the concepts of physics quite easily, but I have a hard time with working mathematical formulas. My wife can do the math, but has a hard time understanding the concepts. We have the same mix with our children, so we looked at https://physicstuitionsg.com to get them some tutoring to make learning all the aspects of physics interesting and fun.
The subject of gear ratios came up when we were having a discussion about multi-speed bicycles. I can easily grasp how a large sprocket would make a smaller sprocket turn faster when connected with a chain. I can also understand the transfer of force to a connected bicycle wheel that makes it harder to pedal, but you go faster, when the large sprocket is turning the small sprocket. I get it how it is easy to pedal when that is reversed. I can picture it in my head as easy as anything, but my wife cannot. Continue reading How to Learn Both Sides of Physics
