A railroad train travels forward along a straight track at 100.0 m/s for 3000 m and then travels at 80.0 m/s for the next 2000 m, keeping the same direction. What is the average velocity? a. 90.91 m/s, forward b. C. d. 90.00 m/s, forward 90.00 m/s 50.00 m/s, forward
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.
