car track

• What is the main objective of the practical described?

  Investigate acceleration of an object
• How does varying the force affect the acceleration of an object?

  It changes the acceleration of a constant mass
• What happens when varying the mass of an object with constant force?

  It affects the acceleration produced
• What equipment is used in the practical?

  Toy car, string, pulley, mass, timer
• What provides the force acting on the toy car?

  The weight of the 100 gram mass
• How are distance markers set up for the experiment?

  Chalk lines at equal intervals
• What should you do when the car is moving rapidly?

  Record the experiment on a mobile phone
• Why is it important to repeat the experiment with decreasing mass?

  To observe the effect on acceleration
• What is the overall object in this experiment?

  Toy car, string, and mass combined
• What does Newton's second law of motion state about acceleration?

  Acceleration is proportional to applied force
• What should you find about acceleration and mass on the string?

  Acceleration is proportional to mass on string
• How can you investigate varying mass affecting acceleration?

  Keep force constant and vary toy car mass
• What mass is used to keep the force constant in the second part of the experiment?

  100 gram mass
• What happens to acceleration as the mass of the toy car increases?

  Acceleration decreases
• What does Newton's second law tell us about mass and acceleration?

  Acceleration is inversely proportional to mass
• How does the setup of the experiment ensure accurate results?

  By keeping mass constant while varying force
