Linear motion occurs along a straight line in one dimension. Can be uniform (constant velocity) or non-uniform (variable velocity). Newton's first law states objects maintain constant velocity unless acted upon by net force
Linear velocity measures speed along a straight-line path. SI unit is meter per second (m/s), common in everyday life (km/h). Basic formula: v = d/t, where d is distance and t is time
Motion is relative and described by displacement, distance, time, and speed. Everything in the universe is in perpetual motion. Motion is essential for all physical processes
Linear motion is movement in a straight line in one dimension. Displacement is the change in position in a specific direction. Velocity is the change in displacement over time. Acceleration is the rate of change of velocity
RVDT converts rotary motion into electrical signal using ferromagnetic core. Consists of hollow cylinder with rotating core between primary and secondary coils. Output voltage varies with core position and rotation direction. Requires external power source and can operate in extreme conditions. Applications include hydraulic pumps, robotics, and process control
Ball screws convert rotational motion into linear motion using ball bearings. Consist of screw shaft, nut, and ball bearings running in helical grooves. Eliminate mechanical contact through rolling friction instead of sliding. Achieve up to 90% efficiency with low energy consumption
