Part A Select the correct "story" about a real object that has the motion diagram shown in the figure. O A car coasts along at 30 m/s and arrives at the edge of the hill. The car speeds up as it coasts down the hill. At the bottom, the road levels and the car continues coasting along the road at an increased speed. O A car coasts along at 30 m/s and arrives at a hill. The car speeds up as it coasts up the hill. At the top, the road levels and the car continues coasting along the road at an increased speed. O A car coasts along at 30 m/s and arrives at a hill. The car slows down as it coasts up the hill. At the top, the road levels and the car continues coasting along the road at a reduced speed.

Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
