A
2
Q
What are the types of linear motion?
A
3
Q
general motion
A
combination of both lin and ang motion
4
Q
rectilinear motion
A
travel in straight line
5
Q
curvilinear motion
A
travel along curved line
6
Q
Give an example of human movement involving the whole body that represents: rectilinear movement,
curvilinear movement, and angular motion.
A
Rectilinear = walk forwards
Curvilinear = bike around velodrome
angular = do a spin in figure skating
7
Q
What does a negative velocity value actually tell you about performance?
A
that the system is travelling to the left
8
Q
What does a negative acceleration value actually tell you about performance?
A
Either: it is slowing down, or it is travelling left
