Uamuzi wa kasi ya mwanga ni daima changamoto kwa vipimo sahihi, tangu Gallileo mia nne iliyopita walidhani kwamba nuru ni kusafiri kwa kasi kidogo.

Maabara mtandaoni yanawapa wanafunzi wako uwezekano wa kuendesha majaribio ya kisayansi katika mazingira ya mtandaoni. Maabara yanayoendeshwa kwa mbali (maabara ya mbali) yanakupa fursa ya kujaribu mitambo halisi kutoka sehemu za mbali. Maabara ya mtandaoni yanapatia uhai mtambo ya kisayansi. Mipangilio ya data inawasilisha data kutoka katika majaribio ya maabara yaliyofanywa awali. Tafadhali tumia vichujio kwenye upande wa kulia ili kupata maabara mtandaoni yanayofaa darasa lako. Maabara yanaweza kuunganishwa kwa Programu tumizi maalum ili kuunda Nafasi za Kusoma za Kiulizio(ILSs).
Ikiwa unatafuta maabara ya mtandaoni hasa yanafaa kwa somo la Benin, Kenya au Nigeria, tafadhali tembelea ukurasa wetu wa Makusanyo.

Katika 1671 anga Kifaransa Richer alisafiri kutoka Paris (latitudo φ = 48.8°) ili Cayenne (latitudo φ = 4.9°) katika Kifaransa-Guyana. Katika Cayenne yeye aliona kwamba saa yake pendulum, ambayo alibeba pamoja naye, alionyesha kuchelewa ya kuhusu 2 min kwa siku.
Hali ya hewa ni umewekwa na usawa maridadi ya mionzi umeme zinazoingia na zinazotoka. Kijiprogramu hiki kwanza inahusu hali ya anga ya sayari mbalimbali, kutizama Mars, Venus na dunia.
Rahisi Harmonic Oscillator JS mfano huonyesha mienendo ya mpira masharti kwa spring na bora. Majira ya kuchipua awali aliweka na mpira ina kasi sifuri awali. Nafasi ya awali ya mpira inaweza kubadilishwa na bofya-kukokota mpira wakati masimulizi umesitishwa.
