dear students, let’s analyze the oblique collision in two dimensional plane . here we are given, 2 balls of masses, m 1 and m 2, moving with initial speeds u 1 and u 2 in different directions, they collide at a point , and, bounce in different directions, with speeds v 1 and v 2 […]

in this example, it is given that a ball is released , from a height h above a floor with coefficient of restitution e , between floor and ball. we are required to find the number of bounces ball will take before coming to rest . and we are also required to find the total […]

in this example we are given two identical bars, which are connected by an ideal spring of natural length l knot, it is also given that its force constant is k , as shown , and a constant horizontal force f starts acting on one of the bars as shown, we are required to find […]

in this example it is given that a neutron moving at a speed v undergoes a head on elastic collision with a nucleus of mass number-a at rest . we are required to find the ratio of ki-netic energies of neutron after and before collision. now, let’s analyze this situation, we are given that a […]

In the previous lecture, we asked you to think about a whole bunch of questions, so let’s go ahead and discuss them. The first question we asked you to think about is what is mathematics? Well if you look at the dictionary meaning of mathematics, it says that mathematics is “the study of numbers, and […]

– This episode of “Because Science” is sponsored by Star Wars: Jedi Fallen Order. The fastest way for humanity to expand into the stars might not involve rockets at all but giant gravitational machines. Let’s get technical. (upbeat techno music) How are we gonna get to other stars? If humanity is to ever expand beyond […]

My name is Andrew Kanarek I am a postdoctoral fellow at The National Institute for Mathematical and Biological Synthesis I’m a theoretical evolutionary ecologist I use matematical approaches to Insvestigate biological phenomena So I’ve been focused on envasive species And I’ve been lately thinking about Endangered species and disease dynamics as well Because all of […]

Amalie Emmy Noether, or Emmy, as she preferred to be called, was born on March 23rd in 1882. Her dad was a professor of mathematics at the University of Erlangen in Bavaria and, as a young girl, she trained in languages. By age 18, she had mastered French and English well enough to be certified […]
