PRACTICAL- motion using light gates

• What is the purpose of using light gates in measuring velocity?

  To measure the time an object spends passing through the light gate
• How do you calculate the velocity of an object using light gates?

  Velocity is calculated using the formula $v =$$\frac{L}{t}$, where $L$ is the length of the object and $t$ is the time spent passing through the light gate
• What measurements are necessary to determine the velocity of vehicle A before the collision?

  Measure the length of vehicle A and the time taken to pass through the light gate
• What steps should be taken to reduce reading errors in velocity measurements?

  Make careful measurements and arrange to minimize reading errors
• What observations and measurements are needed to measure the velocities of vehicles A and B after the collision?

  • Measure the length of both vehicles accurately
  • Use a data logger connected to a light gate to measure the time taken for each vehicle to pass through
  • Calculate the velocities using the formula $v =$$\frac{L}{t}$
• What is the formula used to find velocity in this practical investigation?

  $v =$$\frac{L}{t}$
• Why is it important to measure the length accurately in this experiment?

  Accurate length measurement is crucial for calculating the correct velocity
• What is the significance of measuring the velocities of both vehicles before and after the collision?

  It helps to analyze the effects of the collision on the motion of the vehicles
• How would you use a data logger in this experiment?

  Connect it to a light gate to measure the time taken for the vehicle to pass through
