Lift Data #### Activity Overview

Students will use authentic data to graph and analyse the altitude of two different lifts over a period of time in order to determine travel time, speed and the number of floors visited.

#### Objectives

• ACMNA208 – Solve problems involving direct proportion. Explore the relationship between graphs and equations corresponding to simple rate problems
• Students learn to use a line of best fit to estimate the gradient and speed of a lift. They also learn to use the gradient formula to determine the slope of a line between two points.

• Acceleration
• Velocity
• Speed
• Distance
• Slope
