acceleration

• What is the main focus of the practical investigation described?

  Investigating acceleration of an object
• How does varying the force affect the acceleration of an object of constant mass?

  It changes the acceleration proportionally
• What happens when varying the mass of an object while keeping the force constant?

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

  A toy car, string, pulley, and mass
• What provides the force acting on the toy car?

  The weight of the 100 gram mass
• How do you record the time the car passes each distance marker?

  By using a timer or recording video
• Why is it better to record the experiment on a mobile phone?

  It allows for accurate time recording
• What should you do after recording the first experiment?

  Repeat the experiment with less mass
• What is the effect of decreasing the mass on the end of the string?

  The force acting on the car decreases
• What is considered the object in this experiment?

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

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

  Acceleration increases with more mass
• What is the relationship between acceleration and mass according to Newton's second law?

  Acceleration is inversely proportional to mass
• What should you do to keep the overall mass of the object the same?

  Transfer mass from the string to the car
• What can you find plenty of in the revision workbook mentioned?
