intro to kinematics Flashcards
1
Q
kinematics
A
study of motion
2
Q
uniform motion
A
constant speed and direction
3
Q
non-uniform motion
A
changing speed and/or direction
4
Q
scalar
A
measured quantity w/o direction
- time, density, mass
5
Q
vector
A
measured quantity with direction
6
Q
distance
A
- scalar
- triangle d
- how far an object travels
7
Q
speed
A
- scalar
- v
- the rate at which distance is changing/how fast
8
Q
position
A
- vector
- d w/ arrow
- an objects location relative to a reference point
9
Q
displacement
A
- vector
- triangle d w/ arrow
- change in position
10
Q
velocity
A
- vector
- v w/ arrow
- rate of change of displacement
11
Q
acceleration
A
- vector
- a w/ arrow
- rate of change of velocity
12

distance/time
13
Q
average speed formula
A
total distance/total time
14
Q
