A certain volcano on the Earth can eject rocks vertically to a maximum height H. How high (in terms of H) would these rocks go if a volcano on a planetary object ejected them with the same initial velocity? The accelerations due to the gravity on the Earth and the planetary object are 9.8m/s2 and 3.1 m/s2, respectively. Neglect the effect of the air on both planets. 답:
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.
