GRAPHS:
WHY DO WE NEED GRAPHS?

Graphs allow people to interpret the results of a study and even make predictions about trends they might see in future data sets.
Interpreting graphs involves understanding what the shape of a curve represents in real life situations.
DISTANCE TIME GRAPHS
Distance-time graphs are a way of visually expressing a journey. With distance on the y-axis and time on the x-axis, a distance-time graph tells us how far someone/something has travelled and how long it took them/it to do so.

SPEED
distance traveled per unit time units: m/s,km/hr,miles/hr
-
-
SPEED VS VELOCITY-velocity is speed in a particular direction
- velocity can be a negative number if moving backwards while speed is always a positive number
-
MOTION
PARAMETERS THAT DESCRIBE MOTION: reference point, acceleration, distance,displacement,speed and velocity
