1. Motion In a Straight Line

   • Inquiry question: How is the motion of an object moving in a straight line described and predicted?
     • describe uniform straight-line (rectilinear) motion and uniformly accelerated motion through:
       • qualitative descriptions
       • the use of scalar and vector quantities
     • conduct a practical investigation to gather data to facilitate the analysis of instantaneous and average velocity through:Information and communication technology capability
       • quantitative, first-hand measurements
       • the graphical representation and interpretation of data
     • calculate the relative velocity of two objects moving along the same line using vector analysis
     • conduct practical investigations, selecting from a range of technologies, to record and analyse the motion of objects in a variety of situations in one dimension in order to measure or calculate:Information and communication technology capability Numeracy
       • time
       • distance
       • displacement
       • speed
       • velocity
       • acceleration
     • use mathematical modelling and graphs, selected from a range of technologies, to analyse and derive relationships between time, distance, displacement, speed, velocity and acceleration in rectilinear motion, including:
       • s=ut+1/2at^2
       • v=u+at
       • v^2=u^2+2as

2. Inquiry question: How is the motion of an object that changes its direction of movement on a plane described?

   • analyse vectors in one and two dimensions to:
     • resolve a vector into two perpendicular components
     • add two perpendicular vector components to obtain a single vector
   • represent the distance and displacement of objects moving on a horizontal plane using:
     • vector addition
     • resolution of components of vectors
   • describe and analyse algebraically, graphically and with vector diagrams, the ways in which the motion of objects changes, including:
     • velocity
     • displacement
   • describe and analyse, using vector analysis, the relative positions and motions of one object relative to another object on a plane
   • analyse the relative motion of objects in two dimensions in a variety of situations, for example:
     • a boat on a flowing river relative to the bank
     • two moving cars
     • an aeroplane in a crosswind relative to the ground
