1
Q
vector (1)
A
physical quantity with size and direction (always state direction and give example such as velocity; acceleration)
2
Q
scalar quantity (1)
A
physical quantity with only magnitude (eg mass, time, distance)
3
Q
displacement (3)
A
change in position from starting position to end position (directly) [VECTOR] [S.I. unit: m] [symbol: s;x;y}
4
Q
distance (3)
A
change in position that measures path taken [SCALAR] [S.I unit: m]
5
Q
speed (3)
A
rate of change is distance over time [distance/time] [S.I unit: m/s or m.s^-1]
6
Q
velocity (3)
A
rate of change in position (displacement) over time [vector] [displacement/time]
7
Q
accelleration (3)
A
rate of change in velocity over time [vector] [Δvelocity/time]
