摘要
We have selected video images from the Apollo 16 mission and analyzed the motion of dust clouds kicked up by the wheels of the Lunar Roving Vehicle (LRV). Applying the equations of ballistic motion, we estimate both the velocity of the dust and the gravitational field strength at the lunar surface. From measurements of the rotation of an LRV wheel, we estimate the speed of the LRV. Such exercises can be useful when discussing ballistic trajectories and angular motion in a high school or introductory level college physics class. (C) 2012 American Association of Physics Teachers.
