He lifts on a spinning circular cylinder, in a freestream with a velocity of 10m/s, which is measured as (L1>L2).
Velocity is the directional velocity of a moving object as a measure of the rate of change of position observed from a particular frame of reference and measured at a particular time reference (eg 60 km/h northward). [1] Velocity is a fundamental concept in kinematics, a branch of classical mechanics that describes the motion of bodies.
Velocity is a physical vector quantity. Both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is called velocity, and its magnitude is a consistent derived unit measured in the SI (metric) system as meters per second (m/s or m⋅s−1). For example, "5 meters/second" is a scalar, but "5 meters/second east" is a vector. An object is said to be accelerating if its velocity, direction, or both change.
