True or False 2) Knowing the position and velocity of a particle allows its future position to be predicted even if its acceleration is unknown. True or False 3) Average acceleration and instantaneous acceleration are always the same. True or False 4) Instantaneous velocity is the derivative of the displacement time function. True or False 5) The slope of the velocity-time graph is the instantaneous acceleration. True or False
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.
