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.

Rock Climber Sliding Down a Smooth Slab 9.6 m Hk =0.72 %3D 56° Consider the rock climber climbing on a smooth slab, as shown above: the coefficient of kinetic friction between the climber's rock shoes and the rock is 0.72 the belayer cannot see the climber who is out of sight beyond the edge of the slab the belayer cannot hear the climber because the wind is blowing very hard The climber loses his footing and slides down the slab from rest. How long after the climber loses his footing does the belayer realize she needs to catch the climber's fall? [answer: about 2.1 s] FNET = ma W = mg g = 9.81 m/s? Ax = vot + ½ at?

Air track: two objects tied together by a string. The figure shows a glider with mass my that moves on a level, frictionless air track in a physics lab. It is connected by a string passing over a small frictionless pulley to a hanging weight with total mass m₂. The string is light and flexible, and it doesn't stretch. (a) Find the acceleration of each object and the tension in the string. (b) What happens to the acceleration when m, is two times heavier than that of m₂? (c) Now my is four times heavier than that of m₂. Calculate the distance between it traveled during the initial period of two (2) seconds after the glider started moving. The tract is long enough for the travel. Show your work that leads to your answer. Explain each step in your work to explanation -quation WILIT T
