2.1 Relative Motion, Distance, and Displacement
If a space shuttle orbits Earth once, what is the shuttle’s distance traveled and displacement?
- Distance and displacement both are zero.
- Distance is circumference of the circular orbit while displacement is zero.
- Distance is zero while the displacement is circumference of the circular orbit.
- Distance and displacement both are equal to circumference of the circular orbit.
