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.
A scooter begins at rest at t0 = 0 seconds. The scooter starts moving, and eventually covers a distance d = 727 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the scooter's motion is in the northern direction
A: What was the scooter's displacement in the northern direction during this period, in meters?
B: What was the scooter's average velocity in in the northern direction vavg,N, in this period in meters per second?
C: If the scooter's final velocity at tf was 12 m/s, what was the scooter's average acceleration in the northern direction, aavg,N, during this period in m/s2?
