Motion Graphs

Speed = d/t

Acceleration = v-u/t

Speed

• measured in m/s

• Displacement = distance travelled in a direction

• Velocity = speed in a direction

Acceleration

• measured in m/s2

• Change in speed / time

• V = final velocity

• u = initial velocity

Motion represented on graphs

• There are two types of motion graphs, and three types of motion. 

• Distance time - Gradient of graph = velocity

• Velocity time - Gradient = acceleration

• Velocity time - Area = distance travelled

Before you work out the total distance travelled, remember....

• area of a square/rectangle = base x height

• area of a triangle = 1/2 x base x height
