scalar quantities |
has magnitude but no direction
eg: speed, distance |
|
|
vector quantities |
have magnitude & direction
eg: displacement, velocity, acceleration |
|
|
displacement |
vector quantity
distance travelled from reference point in stated direction
SI unit : m |
|
|
velocity |
vector quantity
rate of change of displacement
SI unit : ms^-1 |
|
|
acceleration |
vector quantity
rate of change of velocity
SI unit : ms^-2 |
|
|
area under graph |
gradient |
|
|
when graph is a flat straight line |
gradient = 0 no/constant gradient |
|
|
when graph is sloping upwards |
increasing positive gradient
constant increasing gradient |
|
|
when graph is sloping downward |
decreasing negative gradient
constant decreasing gradient |
|
|
when the graph is curving upwards |
increasing positive gradient
increasing gradient -> increase more every time |
|
|
when graph is curving downwards |
decreasing negative gradient
decreasing gradient -> decreasing more every time |
