A ball is thrown upward and caught when it comes back down. In the presence of air resistance, what is the ball's speed when it is caught? 1. more than the speed it had when thrown upward 2. less than the speed it had when thrown upward 3. the same as the speed it had when thrown upward 1. more than the speed it had when thrown upward 2. less than the speed it had when thrown upward 3. the same as the speed it had when thrown upward
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.
