Objects moving along a circular path have a centripetal acceleration provided by a net force directed toward the center. Identily Li centripetal acceleration in each of these cases: a planet in circular orbit around its sun; a car going around an unbanked, circular turn; a rock tied to a string and swung in a vertical circle, as it passes through its highest point; and a dry sock in a clothes dryer as it spins in a horizontal circle. (Select all that apply.)

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.
