A car is traveling at 20 m/s. At t = 0 s, it begins to slow at a constant rate so that its speed is 15 m/s when it has traveled 25 m from its position at t = 0 s. What is the magnitude of the car's acceleration? 3.5 m/s2 13 m/s2 0.50 m/s2 7.0 m/s2 0.29 m/s2
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.
