Required Practical 7:Acceleration

• 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 is investigated when varying the mass of an object?

  Effect on acceleration with constant force
• 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 do you record the time accurately during the experiment?

  Record a video and play it back
• What happens to the car when it is released?

  It accelerates along the bench
• Why do we decrease the mass on the end of the string?

  To investigate the effect of changing force
• What is considered the object in this experiment?

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

  It is proportional to the applied force
• What happens to acceleration as the mass on the string increases?

  Acceleration of the toy car increases
• What is the relationship between acceleration and mass according to Newton's second law?

  Acceleration is inversely proportional to mass
• What happens to the acceleration when the mass of the toy car is increased?

  Acceleration decreases
• What are the steps to carry out the practical investigating acceleration?

  1. Set up equipment: toy car, string, pulley, mass.
  2. Hold car at starting point and release.
  3. Record time as car passes markers.
  4. Repeat with decreasing mass on string.
  5. Analyze how force affects acceleration.
  6. Investigate effect of mass on acceleration.
• What are the key concepts related to Newton's second law in this practical?

  • Acceleration is proportional to force.
  • Acceleration is inversely proportional to mass.
  • Force is provided by the weight of the mass.
