Biomechanics year 2 - linear motion Flashcards
1
Q
Define linear motion
A
Movement of a body in a straight or curved line, where all parts move the same distance, direction and time
2
Q
How does linear motion occur
A
Results from a direct force through the COM of a body
3
Q
What are the 5 key factors of linear motion
A
1 - Distance
2 - Displacement
3 - Speed
4 - Velocity
5 - Acceleration/ deceleration
4
Q
Define distance
A
The total length of a path / route covered from start to finish
5
Q
What is the distance of a 100m run
A
100m
6
Q
Define displacement
A
The shortest straight line route from start to finish
7
Q
What is the displacement of a 200m swim
A
0m (4x50m)
8
Q
Define speed
A
The rate of change in distance
9
Q
Define velocity
A
The rate of change in displacement
10
Q
What is the equation for velocity
A
Velocity (m/s) = Displacement (m) / Time (s)
