Physics (Final Exam)

QuestionAnswer
Jika pada gerak translasi adalah massa (m), maka pada gerak rotasi adalah.... momen inersia (I)
Momen inersia bergantung pada.... massa dan jarak dari benda ke sumbu putar
Persamaan momen inersia benda titik yang berotasi I = m*r^2 = m*r^2*sin^2(theta)
Jika pada gerak translasi adalah kecepatan (v), maka pada gerak rotasi adalah.... kecepatan sudut/kecepatan angular (omega)
Jika energi kinetik pada gerak translasi adalah EK = 1/2*m*v^2, maka energi kinetik rotasi adalah.... EK = 1/2*I*(omega)^2 = 1/2*momen inesia*(kecepatan angular)^2
Jika pada gerak translasi adalah gaya, maka pada gerak rotasi adalah.... Momen gaya/torque/torsi
Persamaan gerak momen gaya/torsi Torsi = jarak dari gaya ke sumbu putar * gaya * sin(theta) = r * F * sin(theta)
Persamaan gaya pada gerak translasi adalah.... F = massa * percepatan = m * a
Persamaan gaya pada gerak rotasi adalah.... Gaya = momen gaya * percepatan sudut F = I * alpha
Persamaan usaha pada gerak translasi Usaha = gaya * jarak tempuh W = F * d
Persamaan usaha pada gerak rotasi Usaha = momen gaya * perubahan sudut W = Tau * theta
