Acceleration

• What is Newton's second law formula?

  F = MA
• What equipment is used to verify Newton's second law in this experiment?

  A track, trolley, and pulley system
• What is the weight force of 100 grams on Earth?

  0.98 Newtons
• How much force does each 10-gram mass exert?

  0.1 Newtons
• What is the purpose of using small masses in the experiment?

  To avoid excessive force on the trolley
• What is the effect of using an air track on friction?

  It reduces friction significantly
• How do we measure the acceleration of the trolley?

  Using a data logger and photo gates
• What is the formula used to calculate acceleration with a data logger?

  Change in speed divided by time
• What is the width of the flag used in the experiment?

  5.3 centimeters
• What is the average acceleration obtained for 100 grams?

  1.258 meters per second squared
• Why is it important to repeat readings in the experiment?

  To ensure reliability of results
• What happens when you remove masses from the hanger?

  You must add them to the trolley
• What is the formula for calculating acceleration using one photo gate?

  a = V² / (2s)
• What is the alternative formula for calculating acceleration using time?

  a = 2s / T²
• Why must measurements be in meters for acceleration calculations?

  To ensure acceleration is in meters per second squared
• What should be plotted on the y-axis of the graph?

  Force
• What does a linear relationship in the graph indicate?

  Direct proportionality between force and acceleration
• How do you find the gradient of the line on the graph?

  Height in Newtons divided by width in m/s²
• What mass was calculated from the gradient of the graph?

  0.766 kilograms
• Why might the calculated mass differ from the actual mass?

  Due to friction and air resistance
• What was the actual mass measured on the balance?

  707 grams
