 1 Compare the way advocates of the impetus theory and the way Galileo accounted for the motion of a body moving at constant speed in a given direction. 2 What would Kepler have considered to be the path of a planet if it were influenced by the anima motrix but was not affected by the magnetism of the Sun? 3 In what sense does an orbiting satellite accelerate even if its speed remains constant? 4 Two forces, oppositely directed, act on a body. The force acting toward the right is twice as strong as the force acting toward the left. Describe the motion of the body. 5 Suppose a person is stranded on a frozen lake of perfectly smooth (frictionless) ice. Think of a method for the person to use to reach the shore of the frozen lake. 6 Suppose that a satellite is given a speed 10% larger than circular velocity. What would be the shape of the trajectory of the body? 7 The tidal force that the Earth exerts on the Moon is stronger than that exerted by the Moon on the Earth. Explain why this is so. 8 The tidal acceleration due to the Moon is twice as large as the tidal acceleration due to the Sun. Show how this leads to a total tidal acceleration about three times as large for spring tides as for neap tides.
