- Elastischer Stoß: v_NA = (m_A*v_VA + 2*m_B*v_VB - m_B*v_VA)/(m_A + m_B) v_NB = (2*m_A*v_VA + m_B*v_VB - m_A*v_VB)/(m_A + m_B)
- Fünf Kernformeln über Weg, Geschwindigkeit und Beschleunigung a*t = v_END - v_BEG 2*s = (v_END + v_BEG)*t 2*a*s = v_END^2 - v_BEG^2 2*s = 2*v_BEG*t + a*t^2 2*s = 2*v_END*t - a*t^2
- Balkenwaage I) m_A*x_1 + 1/2*m_S1*x_1 = m_B*x_2 + 1/2*m_S2*x_2 II) m_S1*L = m_S*x_1 III) m_S2*L = m_S*x_2 IV) x_1 + x_2 = L V) m_A*L*x_1 + 1/2*m_S*x_1^2 = m_B*L*x_2 + 1/2*m_S*x_2^2 VI) (m_A + 1/2*m_S)*x_1 = (m_B + 1/2*m_S)*x_2 x_1 = 1/2*(2*m_B + m_S)/(m_A + m_B + m_S)*L x_2 = 1/2*(2*m_A + m_S)/(m_A + m_B + m_S)*L
- Beschleunigter Luftkasten I) rho_V = rho_H*exp(-rho_0*g/p_0*L) II) rho_H - rho_V = rho_0*ln(rho_H/rho_V) ----------------------------------------------- III) rho_H = rho_0^2*g/p_0*L/(1-exp(-rho_0*g/p_0*L)) IV) rho_V = rho_0^2*g/p_0*L/(exp(rho_0*g/p_0*L)-1)
