acceleration rq 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 while keeping the force constant?

  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 the car passes each distance marker?

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

  It allows for accurate time recording
• What happens to the force when the mass on the end of the string decreases?

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

  The toy car, string, and mass together
• How do you keep the overall mass of the object constant?

  Transfer mass from the string to the car
• According to Newton's second law, how is acceleration related to force?

  Acceleration is proportional to the applied force
• What does the weight of the mass on the string represent in this experiment?

  The force applied to the toy car
• What happens to acceleration as the mass of the toy car increases?

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

  Acceleration is inversely proportional to mass
• What should you expect to find when increasing the mass of the toy car?

  Acceleration decreases as mass increases
• Where can you find more questions on this practical investigation?
