Are speed, velocity and acceleration related together. How does distance and displacement affect these variables

Environment and Homofaber. How will inventions tn transportation affect the environment and influence the cultural context?

What are speed and acceleration? Scalars and Vectors. Use of graphs (displacement – time / speed – time)

Content/contenido

Students will be able to:

•  define and calculate speed from total distance / total time,
•  plot and interpret a speed / time graph,
•  recognise from the shape of a speed / time graph when a body is (a) at rest (b) moving with constant speed (c) moving with changing speed,
•  calculate the area under a speed/time graph to determine the distance travelled for motion with constant acceleration,
•  demonstrate some understanding that acceleration is related to changing speed,
•  state that acceleration of freefall for a body near the Earth is constant.

End of unit assessments, internal assessment and practical assessments.
