Acceleration practical

• 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?

  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 investigation?

  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 the experiment on a mobile phone
• Why is it important to decrease the mass on the end of the string?

  To investigate the effect of changing force
• 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?

  Acceleration is proportional to the force applied
• What is the relationship between acceleration and the mass on the string?

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

  Attach mass to the toy car
• 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
• Where can students find more questions on this practical?
