kinematics deals with what components of motion
spatial and temporal
linear motion is also known as
translation
straight line= what motion
curved line = what motion
- rectilinear
- curvilinear
in angular motion different parts of the object undergo different ? displacements but the same ? displacement?
- linear
- angular
a combo of linear and angular motion
general motion
in image analysis, the coordinate system usually involves a calibration using ? to actual units of measurement
pixels
in 3D optical motion capture reflective markers are placed on person and the position is determined by the ? of the position marker relative to at least 2 cameras
triangulation
2 vectors that are parallel
colinear vectors
vectors that do not have points along the same line
non colinear vectors
equation for linear speed and linear velocity and linear acceleration
- linear distance/ change in time
- linear displacement/ change in time
- change in linear velocity / change in time
3 ways to measure basic linear kinematics
- vid analysis
- infrared timing gates
- inertial measurement units
3 types of inertial measurement units
- accelerometer (3D)
- gyroscope (rotation)
- magnetometers ((orientation)
the time between the previous and current distance
split time
