A student holds a ball 1.55 meters above the ground and drops it. Her friend uses a stopwatch and measures a time of 0.57 seconds for the ball to hit the ground. Using the equation y = 1/2gt2. The ball accelerates due to gravity and the acceleration of the ball is 9.54m/s2. Calculate the percent error between the acceleration you obtained and theoretical value of g.
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.
