4) you throw a ball upward. Once the ball leaves your hand 4a) on the way up, the ball slows down and comes to a stop momentarily therefore the acceleration of the ball is downward (T, F) 4b) the acceleration of the ball the moment the ball is at rest at the highest point is zero (T, F) 4c) the direction of the acceleration of the ball points down while the ball is rising or falling (T, F)
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.
