This video is a review of circular motion and gravitation for AP Physics 1.

Lesson 12 (Conservation of Momentum) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you!

Exercises in this video:
1. Compare the momenta of two objects: one with a mass of 260kg moving at 20m/s, and the other with a mass of 1950kg moving at 1m/s.

2. What are two different (common) ways to represent the units of momentum?

3. You and your spherical space cow push off of each other, in space. The cow, which has a mass of 100kg, ends up with a speed of 2.5m/s. Your mass is 50kg. What will your velocity be after the push?

4. What is the total impulse of a rocket that thrusts with a force of 7600kN for 162 seconds?

Special thanks to Cheyenne Polius for her awesome shoutout at the end of the video!
And thank you to the Planetary Society for allowing us to use the footage for their awesome light sail.

Modern physics is an effort to understand the underlying processes of the interactions with matter, utilizing the tools of science and engineering. In general, the term is used to refer to any branch of #physics either developed in the early 20th century and onward, or branches greatly influenced by early 20th century physics. Notable branches of #modern_physics include quantum physics, special relativity, and general relativity.


This course contains almost everything you need to know about modern physics.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This is a new HD motivational trailer choreographed to powerful music that introduces the viewer/student to the wonder of Physics. It is designed as a dramatic inspirational trailer to be shown in class by Physics and Science teachers in middle and high school and college as a visual "Introduction" to this amazing science. I promise your students will love the video and be ready to learn about the many topics in Physics you will offer.

Subscribe to my channel at https://www.youtube.com/user/sfgregs to see all of my exciting video trailers in Biology, Chemistry, Earth Science, Astronomy, Physics and Math. I will be releasing new ones periodically.

Please rate this video and leave a written comment. If you like it, please help me spread the word by posting links to it on your school and social media websites. The more students and teachers who can enjoy these dramatic videos, the better!

I wish to thank all the quality video and music producers whose postings enabled me to produce this video for educational use.

To best enjoy this video, view on a big screen and turn up your speakers. The music is powerful and dramatic!

I can customize this video to add your name or school name at the end credits, for a very modest fee. If interested, email me at "fsgregs@comcast.net".

The music is "Whispers of Wonder", by Audiomachine.

رحب بالعداوات | بودكاست د.ياسر الحزيمي

تُعد الصحة النفسية من المواضيع المهمة جدا لي وللكثيرين، وأجد أن أحد أهم مقومات الصحة النفسية العلاقات الإنسانية.
وللحديث أكثر عنها، استضفت ياسر الحزيمي مدرب معتمد ذو خبرة في تقديم الدورات والمحاضرات في مجال تطوير العلاقات ومهارات
الاتصال».
يقول الحزيمي: العلاقات لازم تدخلها معك سيف وغمد ودرع.» مشيرًا إلى أن الإنسان ينبغي أن يحقق التوازن في علاقاته، دون زيادة في لطف يكسره أو عنف يبعد الآخرين عنه.
ثم حدثني عن أهم أركان العلاقات الإنسانية، فما تعاملنا مع الآخرين سوی انعکاس لعلاقتنا مع الله، وكذلك علاقتنا بأنفسنا. كما ذكر لي الشكل الصحيح للعلاقات، فينبغي للشخص ألا يُظهر نفسه بهيئة بعيدة عن حقيقته، ويؤكد أن ذلك من الأسباب التي تؤدي إلى الحزن والاكتئاب.
كما سألته عن حب الذات والفرق بينه وبين الغرور ثم انتقلت في حديثي معه إلى الفردانية وانحسار العائلة والعلاقات الإنسانية في ظل وسائل التواصل الاجتماعي. واختتمنا الحلقة بالحديث عن العلاقة بين الجنسين في الزواج أو بيئات العمل في ظل تغير المجتمع.
#ياسرالحزيمي #بودكاست #فنجان #بودكاست_فنجان #العلاقات

نتحاور في هذه الحلقة عن اضطراب ما بعد الصَّدمة. فما هي أنواع الاضطرابات المرتبطة بالصَّدمة؟ وما هي أعراض اضطراب ما بعد الصَّدمة وأسبابه؟ وما علاقته مع الاضطرابات النَّفسيَّة الأخرى؟ وما كيفيَّة علاجه والتَّعامُل معه؟

#وفي_أنفسكم مع استشاري الطب النفسي د. أنس بن عوف وياسر الحزيمي.
