@prof_preobr Много лет язык тренировал. Теперь глубже всех может лизнуть.

@TulsiGabbard Boys in elementary schools do not produce sperm and girls do not produce eggs. Stop these uneducated "educators" who do not know human biology.

@LouieKlein_ I think it is a significant rotational inertia of the wheels. My colleague believes that students started stopwatch earlier than the cart starts moving.

@BPhysicswith @ChatPhysics Using paper protractors is much easier. BTW I put them empty in the water to show total internal reflection.

@a_freeparticle Great set of problems, thank you. Just change a picture for #8, please, to avoid the vertical part of the wall on the right or you need to give its height due to the zero friction.

- Президент подготовил специальный призыв к миру, который планировали к показу сегодня перед финальной игрой футбольного чемпионата.

Президент обратился ко всему человечеству с инициативой провести Глобальный саммит мира.

Просьба - распространить.

@AllysonApsey @burgessdave @dbc_inc @TaraMartinEDU @burgess_shelley Positive relationships. This year especially, because the school made me a science dept. head

@SJDJ @DShanzer I bought them. They are curved, not really model vectors.😞

I like almost all #Vernier sensors. My favorite so far is Diffraction Apparatus.

@BarnettDreyfuss It is a resonance tube with a broken main part - the tube itself. The wider glass tube connects to the metal cup with a hose. By moving metal cup you can change a water level in the glass pipe that is broken in your remnants of the apparatus.

@SecaurPhysics Some people forgot that teachers are human beings. If you show no emotions or opinions, students will never trust you.

I made a better setup for my planetary transit demo using @VernierST Centripetal Force Apparatus and @VernierST Light Sensor and converted it to an astronomy lab. Worked great, students were excited.

My new blog post on modeling planetary transit lab using Vernier equipment. This lab was a big success in my Astronomy IB class. #Vernier #Astronomy_Education https://t.co/zxDEsnQGQu

@sea_inside3 Геббельс отдыхает и сгорает от зависти. Давить эту российскую нечисть, иначе она начнет распространяться. Слава Україні!

@Jvvk80 @mathssolutionz You missed -pi/2.

[Boris Ovetsky🇺🇦🇺🇸 @BorisOvetsky]

@CNickerson912 Great. If you zoom in, you will see almost perfect graph for friction force vs time, which in reality friction vs applied horizontal force.

[Boris Ovetsky🇺🇦🇺🇸 @BorisOvetsky]

Today we try to find coefficients of friction a new way that was proposed by one lab group of students. We used constant velocity carts to move different blocks and looked at the graphs of friction that we got with @VernierST force probes. #APP1 #physics
