Q1.2 - Astronaut David Scott dropped a hammer and a feather at the same time on the Moon, from a height of 1.20 m and observed them hit the lunar soil at the same time. The surface gravity of the Moon gives a constant acceleration of 1.62 m s-² d. How long did it take for the objects to hit the surface of the Moon after their release? e. What was the speed of the objects as they hit the surface of the Moon?
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.
