Block-on-Block can be confusing. We make it easy. In this numerical solved problem, a "system of two blocks" is sliding together on a perfectly frictionless horizontal ground plane.

The question is to find the right amount of Force to keep the Upper Block sticking to the Lower Block , in other words, the Upper Block should NOT SLIDE with respect to the Lower Block.

We have used FREE BODY DIAGRAMS, the explanation will give you confidence on how to use them. The Free Body Diagrams need a little bit of patience to create, but once it's done, it will be easier to line up the Forces acting in various axes X,Y and Z, and then do a vector addition/subtraction ...


This rule connects three things :- 1) a magnetic field direction, 2) a current flow direction, 3) a Force direction on a conductor. The Fleming’s Left Hand Rule is about getting the right directions. In a situation where all these 3 things exist, the starting point is that you take your left Hand and then point precisely towards the direction of the magnetic field. 1. keep only your forefinger pointing in the direction of magnetic field. 2. turn your middle finger to point in the direction of current ....


Light is really really fast, and a light beam travels at a velocity of 299792. 458 km/second. We can say it’s close to 300,000 km/second. The light from the sun reaches us after8 minutes and 20 seconds. This velocity is the same for every colour of light, violet to red, and hence is independent of wavelength or frequency. Measuring this kind of speed was a great challenge for scientists, at that time, using available technology of clocks to measure a time interval. Fizeau showed a brilliant method. He used an experimental setup which from one end to the other end needed 8.6 miles (13.84 km). That’s not much at all, considering that even...
