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.
How high up would you have to be to see a significant difference in the acceleration due to gravity? Explain.
The acceleration due to gravity is approximately 9.81 m/s2 at sea level. As we move away from the Earth's surface, the distance between the center of the Earth and the object increases, and the force of gravity acting on the object decreases.
The acceleration due to gravity at surface of earth = ,
The acceleration due to gravity from height h from surface of earth =
Radius of earth =
