Because his girlfriend breaks on him, a boy climbs to the rooftop of the school building. He throws a piece of chalk at his ex-girlfriend passing below him. What is the acceleration of the chalk? * 1m/s2 5m/s2 -9.8 m/s2 9.8 m/s2 A hockey puck is hit by a stick and slides off at an initial speed of 0.5 m/s. Assuming that the ice is frictionless, what is the speed of the puck after 1s? * 0.5 m/s 5 m/s O 10.5 m/s 50 m/s
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.
