A record of travel along a straight path is as follows: 1. Start from rest with constant acceleration of 2.88 m/s2 for 19.0 s. 2. Maintain a constant velocity for the next 1.10 min. 3. Apply a constant negative acceleration of ?8.05 m/s2 for 6.80 s. (a) What was the total displacement for the trip? m (b) What were the average speeds for legs 1, 2, and 3 of the trip, as well as for the complete trip?
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.
