• TLF-IDL10090

Explore the graphs of linear equations in the form y = mx + c. Observe changes to the gradient and y-intercept under various transformations. Alternately, change the equation and observe changes in the y-intercept or change the y-intercept and see how the equation changes.

Compile a news article reporting results of a major triathlon. Look closely at graphs of a triathlete's performance (distance against time and distance against altitude) for the cycling leg of a course. Interpret the graphs to answer questions about the triathlete's peformance and the altitude of the course. Insert your ...

• TLF-IDL758

Compile a news article reporting results of a major triathlon. Look closely at graphs of a triathlete's performance (distance against time) for the swimming, running and cycling legs of the course. Interpret the graphs to answer questions about each of the race legs and the overall performance of the triathlete. Insert ...

• TLF-IDL7820

Observe the non-linear distance–time graph of a rocket travelling at a changing velocity. Calculate the average and instantaneous velocity of the rocket over different time intervals. Notice how as each time interval becomes smaller, the rocket's average velocity approaches its instantaneous velocity. Use the slider to ...

• TLF-IDL7822

Observe the non-linear graphs of various power functions (such as f(x) = x², or f(x) = x³) and select the expressions for finding the gradient of the secant between small changes in x represented by Δx. Tabulate the values of f'(x) and plot the derivative of each function. Determine the pattern between the graphs for each ...

• TLF-IDL7824

Observe the non-linear distance–time graph of a rocket travelling at a changing velocity. The distance, s, travelled by the rocket after t seconds is determined by the formula s(t) = t⁴ + t². Calculate the average velocity of the rocket over time intervals that become progressively shorter. Tabulate the results and look ...

• TLF-IDL7826

Observe the linear and non-linear distance–time graphs of a rocket travelling at both constant and changing velocities. Calculate the average and instantaneous velocities of the rocket over different time intervals. Notice what happens to the average and instantaneous velocities as the time intervals become smaller. Work ...

• TLF-IDL7828

Observe the non-linear time graph of a rocket travelling at a changing velocity. The distance, s, travelled by the rocket after t seconds is determined by the formulas: s(t) = t³ – 2 and s(t) = t⁴ + t². Calculate the average velocity of the rocket over time intervals that become progressively shorter. Tabulate the results ...

• TLF-IDR11202

Learn to use your knowledge of graphs and calculus to analyse the way things move. Follow the derivation of equations to describe the position, velocity and acceleration of a moving object. Deal conceptually with both positive and negative accelerations. This resource consists of a video in three sections with animations ...

Use this resource with 'Triathlon: assessment' (L8274). First, see a profile of that assessment object, which gives you some helpful background information. Then follow clear guidelines on the interpretation of student's responses to questions based on interpreting information on a distance–time graph in the assessment object.
