Correctly match the following graph titles to their expected shape.

Which of the following shows the correct relationship between the linear acceleration () of the hanging mass and the tension force () in the string?

Match the following terms and their description, with reference to the experimental apparatus.

For the second experiment, why would we use just a 10g mass, instead of the 50g mass from the first experiment?

For this question, consider a diagram of the experiment setup when viewed from the side:

The hanging mass has a mass of 'm'.

Which of the following diagrams correctly identifies the forces on the hanging mass and string, in the correct directions?
