Intro Flashcards
Kinematics
Describes motion w/o consideration of the forces that cause motion (what u see, spacial and temporal)
Kinetics
Concerned w the forces producing motion or maintaining equalibrium
Rotary motion
Movement of a segment around a fixed axis in a curved path
all points on the object stay the exact distance from the axis of rot
Translatory Motion
movement of a segment in a straight line
Curvilinear motion
Rotary and translatory combined
- all points move sance distace but along curved path
General motion
Combo of rot and translation
-almost all human movement
what two movements make up linear kinematics
Straight line
Curvilinear
scalar vs vector
scalar- quantities measured by their magnitude (mass, distance)
Vector- described by both magnitude and direction
is distance scalar or vector
scalar
What is velocity
vector
displacement/time
is speed scalar or vector
sscalar
what is acceleration
vector
change in velocity/time
Angular displacement vs angular distance
displacement- difference bw the initial and final po
Distance- total of all angular changes measured following its exact path
if you want a big Vt(linear velocity) what are the two things u could do
Have a big r= limited by hieght/club length
A fast omega= swing fast
what is centripetal acceleration
object accelerating towards the axis
