You decide to flip a coin to determine whether to do your physics or English homework first. The coin is flipped straight up. (a) If the coin reaches a high point of 0.25 m above where you released it, what was its initial speed? (b) If you catch it at the same height as you released it, how much time did it spend in the air? Hint: The time it takes the ball to rise equals the time it takes to fall.
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.
