Consider the following data for the table below: • Distance travelled by the cart = 119 cm • Height of inclination = 21 cm • Average Time of Travel = 1.013 s Acceleration down the Inclined Plane Height of Time of Travel (s) Acceleration (m/s²) sin e Track (cm) Trial 1 Trial 2 Trial 3 Average Experimental Theoretical Error (B) (A) (C) (D) Length of Track: Calculate the percent error between the theoretical and experimental acceleration of the cart down the incline in (D). 29.1% 25.4% 35.9% 34.1%
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.
