Kinematics Flashcards
1
Q
vector
A
physical quantity that has both magnitude and direction
e.g. displacement. velocity, impulse
2
Q
scalar quantity
A
physical quantity that has magnitude only
e.g distance, speed, work
3
Q
resultant vector
A
the single vector which has the same effect as the original vectors acting together
4
Q
distance
A
length of path travelled
scalar
5
Q
displacement
A
change in position
vector
6
Q
speed
A
rate of change of distance
scalar
7
Q
velocity
A
rate of change of position / rate of displacement / rate of change of displacement
(vector)
8
Q
acceleration
A
the rate of change of velocity
