A stone is thrown straight up from the edge of a roof, 650 feet above the ground, at a speed of 16 feet per second. A. Remembering that the acceleration due to gravity is −32ft/sec^2, how high is the stone 5 seconds later? B. At what time does the stone hit the ground? C. What is the velocity of the stone when it hits the ground?
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.
