O que acontece quando ATIRAMOS para CIMA? Você já se perguntou o que acontece com uma bala disparada para o alto? No vídeo de hoje, respondemos à dúvida e explicamos todo o trajeto da bala: desde a velocidade inicial, de cerca de 900 km/h, até o momento em que ela atinge a velocidade terminal, por volta de 200 km/h, ao cair. Descubra como a resistência do ar e a gravidade influenciam esse movimento e por que disparos para cima são tão perigosos. #curiosidades #física #tiro #manualdomundo

PODEMOS realmente VIVER em MARTE? Colonizar Marte parece incrível, mas será que é realmente viável? Tecnicamente, sim, mas o desafio é gigantesco! O principal problema é que não dá para mandar suprimentos o tempo todo, pois Marte e a Terra só se alinham a cada dois anos. Isso significa que os astronautas teriam que sobreviver sem apoio externo, reciclando água, cultivando alimentos e lidando com emergências por conta própria. #Marte #Espaço #ciência #Nave
