Physics Tuition Singapore A Level/H2/H1 Physics Tuition – Upthrust, Drag Force, Weight   A ball is falling at terminal speed in still air. The forces acting on the ball are upthrust, viscous drag and weight. What is the order of increasing magnitude of these three forces? A     upthrust → viscous drag → weight B     viscous drag → upthrust → weight C     viscous drag → weight → upthrust D         weight → upthrust → viscous drag   Answer : A At terminal velocity, U + D = W For a ball in air, U is very small, hence U < D < W   Please contact Angie @ 96790479 or Mr Ong @ 98639633 if you need Physics Tuition in A level/H2/H1
