Introduction

Topics

Kinematics

Speed, velocity and acceleration

Graphical analysis of motion

Sample Learning Goals

(e) plot and interpret a displacement-time graph and a velocity-time graph

(f) deduce from the shape of a displacement-time graph when a body is:

(i) at rest example of progressive mathematical model is encouraged X = 0

(ii) moving with uniform velocity example of progressive mathematical model is encouraged X = 1*tf or a constant velocity motion of v =1 m/s

(iii) moving with non-uniform velocity example of X = 0.5*1*t^2 for a constant acceleration motion of a =1 m/s^2

(g) deduce from the shape of a velocity-time graph when a body is:

(i) at rest

(ii) moving with uniform velocity

(iii) moving with uniform acceleration

(iv) moving with non-uniform acceleration

Interesting Fact 2

This app is produce real numbers to coincident with the real world data of gravity pull at 9.81 m/s^2 with some random errors simulating real data-logger results. There is a mathematical modelling pedagogy built into the simulation for students to make effort to represent the physics similar to Tracker's particle modeling.
