# Year 11 – Kinematics

##### Motion in a Straight Line
• describe uniform straight-line (rectilinear) motion and uniformly accelerated motion through
• qualitative descriptions

Resource – Qualitative and Graphical Descriptions – 2 pages

• the use of scalar and vector quantities (ACSPH060)
• conduct a practical investigation to gather data to facilitate the analysis of instantaneous and average velocity through:
• quantitative, first-hand measurements
• the graphical representation and interpretation of data (ACSPH061)
• 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:
•
• time
• distance
• displacement
• speed
• velocity
• acceleration

Investigation – Falling Objects – 4 pages

• 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:
• $s = ut + \frac{1}{2}at^{2}$
• $v = u + at$
• $v^2 = u^2 + 2as$ (ACSPH061)

Resource – Equations of Motion – 2 pages

##### Motion on a Plane
• 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 (ACSPH061)
• represent the distance and displacement of objects moving on a horizontal plane using:
• resolution of components of vectors (ACSPH060)

Resource – Vector Components – 2 pages

• describe and analyse algebraically, graphically and with vector diagrams, the ways in which the motion of objects changes, including:
• velocity
• displacement (ACSPH060, ACSPH061)
• describe and analyse, using vector analysis, the relative positions and motions of one object relative to another object on a plane (ACSPH061)

Resource – Relative Velocity (Part 1) – 2 pages

• 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 (ACSPH060, ACSPH132)

Resource – Relative Velocity (Part 2) – 2 pages
