... • How and why objects move as they do has fascinated scientists for thousands of years. • In the early 1600s, the Italian astronomer Galileo Galilei suggested that, once an object is in motion, no force is needed to keep it moving. • Force is needed only to change the motion of an object. • Galileo ...

... 1. During a relay race, runner A runs a certain distance due north and then hands off the baton to runner B, who runs for the same distance in a direction south of east. The two displacement vectors A and B can be added together to give a resultant vector R. Which drawing correctly shows the resulta ...
