9. If you drop a 4.3 kg rock off the top of a building that is 187 m high, how long will it take to reach the ground? 10. What will be the velocity of the rock from problem 9 when it reaches the ground? 11. If the rock from problem 9 was tossed straight up over the edge of the cliff with a velocity of 6.7 m/s then how long will it take the rock to reach 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.
