1. Impulse and quantity of movement.  In dynamics exercises there are occasions in which force is not the most convenient magnitude to use. This happens in problems of crashes, explosions, rockets that take off and whose mass varies due to the fuel consumption, etc. On these occasions we use the quantity of motion. We are going to read section 7.4 of our notes of dynamics and we are going to work the following videos:
Well, when solving problems, when the force is not well known or an alternative form is preferred, applying the principle of conservation of energy generally simplifies the calculations. Among the advantages of working with energies instead of forces is that they are scalar and not vector quantities.

Each of you may have many reasons to consult the blog, but we know that two of them are the most common, either languages resist you or you love them, maybe even a mixture of both.
But in reality this is something that can happen to you with many other subjects, although we all know that, along with languages, it is the sciences that give students the most headaches. And yes, by science we mean mathematics, physics, chemistry?
Unicoos is an online academy, and in it you will find tutorials, doubt forums and solved exercises, everything you need to be able to deal with subjects that at first may seem impossible, but with the creativity, dedication and passion dedicated by this great team, they can become your great allies.
Consulting their website you can see the satisfaction and gratitude of their students, demonstrating that their formula works…and that you can fail or make a mistake, but you can’t give up and even less now that you have this excellent help. Registering is very easy and with the use of the platform, participating in forums or watching videos, you accumulate a series of merits and medals that make you appear on the website.

Today, we share with you a post about Unicoos, a portal on YouTube, which has more than 600 free videos of general science subjects, such as: Mathematics, Physics, Chemistry, and Technology focused for high school and higher education students.
The Unicoos portal also has its own Web Platform – UNICOOS where students can find digital resources such as solved exercises, notes, self-assessment tests, a gamification area, and an online forum in real time to resolve doubts and answers to the videos exposed in the tool.
The videos are recorded in high definition and with a very good sound quality, and they try to introduce as much as possible graphic effects and film excerpts or other fragments that have to do with the explanation given.
