That would be an Accelerometer.
Velocity
The unit for air resistance is Newtons (N), which measures the force exerted by air on an object in the opposite direction of its motion.
A pedometer measures the distance walked in a given time. This works by the motion of the unit.
Speed, velocity, and acceleration are common quantitative measures used to describe motion. Speed is the distance traveled per unit of time, velocity specifies both speed and direction, and acceleration measures the rate of change of velocity.
The velocity of an object, in a given direction, is a vector which measures the change in position, in that direction, per unit of time.
electronic control unit
Velocity is the measure of an object's change in position per unit time. It indicates both the speed and direction of motion.
Electronic control unit or computerElectronic control unit or computer
The unit that measures wave frequency is hertz (Hz).
The S.I unit of motion is Newton
The full form of IMU is Inertial Measurement Unit. It is an electronic device that measures and reports a body's specific force (acceleration) and angular rate.
A processing unit is a systematic, electronic device that can "think" for itself using codes and electronic sequences.
