An astronaut is doing an experiment on a planet that he does not know about gravitational acceleration. In his first measurement, he drops a stone from the edge of a cliff at a certain height in a vertical direction (initial velocity = 0). It takes 4.15 seconds for the stone to fall to the ground. In the second measurement, he throws another stone from the same height with a certain first speed, this time upwards in a vertical direction, the stone rises up to 2 meters from the position where it was thrown and hits the ground 6.3 seconds after it is thrown. What is the gravitational acceleration of the planet?
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.
