Graphical Method

• What is the purpose of the graphical method in this context?

  To calculate the value of the acceleration of freefall
• What is the first step in the graphical method?

  Measure the height of the fall with a ruler
• How should the time of fall be recorded?

  Using a stopwatch
• What should be plotted on the graph's y-axis?

  Height of the fall
• What should be plotted on the graph's x-axis?

  Time of fall
• What analysis is used to find the acceleration due to gravity (g)?

  Using gradient analysis
• What is the relationship between the gradient and g in the context of this method?

  Gradient = g/2
• What units are used for the acceleration of freefall?

  m/s²
• What is the significance of the data obtained from the first three methods?

  It is used to calculate the acceleration of freefall
• What are the steps involved in the graphical method for calculating freefall acceleration?

  1. Measure the height of the fall with a ruler.
  2. Record the time of fall using a stopwatch.
  3. Plot a graph with height on the y-axis and time on the x-axis.
  4. Use gradient analysis to find g.
