What is a vector quantity
a quantity that has magnitude (size)
a quantity that has direction
a quantity that has magnitude or direction
a quantity that has magnitude and direction
What is the significance of a negative vector?
It's less than 0
It's in the opposite direction to motion
It's in the opposite direction to the direction we chose as positive
It's in the same direction as the direction we established as positive

The x-axis represents the speed
The y-axis represents the time
The y-axis represents the speed
On this graph, the flat line from 100 to 110 mins...
means the object is not moving
means the object is moving with a constant positive speed
means the object is moving with a constant negative speed
On this graph, the positive gradient lines from 0 to 50 mins...
mean the object is not moving
mean the object is moving with positive speed
mean the object is moving with positive velocity
mean the object is moving with negative speed
mean the object is moving with negative velocity
On this graph, the negative gradient line from 50 to 100 mins...
means negative speed
means negative displacement
means negative velocity
At t=50 minutes...
the object has a speed of exactly 30 meters per second.
the object has a velocity of exactly 30 meters per second.
the object has a displacement of exactly 30 meters.
Just after t=20 mins
it speeds up
it slows down
it stops
it starts moving backwards
After 50 mins...
it speeds up
it starts moving backwards
both of the above
