Linear Kinematics Flashcards
1
Q
translatory motion
A
rectilinear
curvilinear
2
Q
rotary motion
A
angular
3
Q
displacement
A
-straight line from point A to B
-pf-pi
-vector quantity
-magnitude and direction
4
Q
distance
A
-path of motion
-scalar quantity
-magnitude but no direction
5
Q
speed
A
-scalar
-change in distance/ change in time
-seconds
6
Q
velocity
A
-change in displacement/change in time
-Pf-Pi/ TIMEf-TIMEi
-m/s
7
Q
quantities - speed
A
-running is the product of stride length and stride frequency
8
Q
acceleration
A
-change in velocity / change in time
-magnitude of acceleration
-direction affects an acceleration
9
Q
average vs. instantaneous acceleration
A
-instantaneous: shrink time interval
