Suppose an object on the moon is thrown from a height of h = 100 m with velocity v = 5 m/s (upward). The acceleration due to gravity on the moon is a = -1.62 m/s². (a) Find the velocity and position of the object as functions of time. (b) How high will the object get? (c) How long will it take the object to hit the ground? (d) How fast will the object be moving when it hits the ground? (e) Convert your answer from part (d) to miles per hour.
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.
