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.
![Mr. Muscedere, Mrs. Muscedere and his daughter are playing a game of tug of war
by pulling horizontally in different directions.
Mr. Muscedere pulls with a force 55N (N].
Mrs. Muscedere pulls with a force of 45N [E55S].
Astoundingly, when his 1.5 year old daughter pulls on her rope, everyone stops
accelerating.
What is the magnitude and direction that his daughter has to pull in order for this to
be true?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fab13d251-d2d7-4657-8ecd-68a32189a896%2F58b07f1c-f692-439c-a1c3-1eec3184aa87%2Fd86uar_processed.jpeg&w=3840&q=75)
