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.
Is the acceleration of an object in free fall changing with time?
is the velocity of an object in free fall changing with time?
Under the free fall condition, The acceleration of the object is equal to the gravitational acceleration which is equal to 9.81 m/s2 and remains constant and doesn't changes with time.
Thus we can say that the acceleration of an object in free fall doesnot changes with time.
