5. Can an object be moving toward the right and the acceleration be pointed toward the left? Explain using an example. 6. A person from rest accelerates at 1m/s2 for 5 seconds. What is the person's velocity at the end of the five seconds? 7. If a car going at 10m/s decelerates (negative acceleration) at -2m/s2, how long will it take for it to come to a stop (0m/s)?
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.
