  1. 1A spring obeys Hooke’s law.

    Which graph is obtained by plotting the extension of the spring against the load applied?
    1. AAImagen de la opción A
    2. BImagen de la opción B
    3. CImagen de la opción C
    4. DImagen de la opción D
  2. 2An experiment is carried out to measure the extension of a rubber band for different loads.
    The results are shown at the left.

    Which figure is missing from the table?
    1. AA 17.2
    2. BB 17.3
    3. CC 17.4
    4. DD 17.6
  3. 3Four objects are each acted on by only two forces, as shown.

    Which object is in equilibrium?
    1. AAImagen de la opción A
    2. BBImagen de la opción B
    3. CCImagen de la opción C
    4. DDImagen de la opción D
  4. 4Different weights are hung from a spring.
    The diagram shows the original length of the spring, and the lengths when different weights are added.
    The extension of the spring is directly proportional to the weight hung from it.

    What is the weight of W?

    1. AA 30 N
    2. BB 35 N
    3. CC 40 N
    4. DD 45 N
  5. 5The extension-load graph for a spring is shown.
    The unstretched length of the spring is 17.0 cm.
    When an object is hung from the spring, the length of the spring is 19.2 cm.

    What is the weight of the object?     Imagen de la pregunta 5
    1. AA 1.4 N
    2. BB 1.6 N
    3. CC 2.6 N
    4. DD 3.0 N
  6. 6Two metal blocks P and Q have identical dimensions. They hang on identical spring balances.

    What can be deduced about P and Q?
    1. AA They have different volumes and different weights.
    2. BB They have different volumes, but equal masses.
    3. CC They have equal volumes and equal weights.
    4. DD They have equal volumes, but different masses.
  7. 7A student adds weights to an elastic cord. He measures the length of the cord for each weight.
    He then plots a graph from the results, as shown.

    What has he plotted on the vertical axis?     Imagen de la pregunta 7
    1. AA measured length
    2. BB original length
    3. CC (measured length + original length)
    4. DD (measured length – original length)
  8. 8The diagrams show a steel spring and a graph of its length against the load applied to it.

    What is the extension of the spring when a load of 20 N is applied to it?     Imagen de la pregunta 8
    1. AA 3.0 cm
    2. BB 4.5 cm
    3. CC 5.0 cm
    4. DD 8.0 cm
  9. 9The diagram shows a handle with three forces, each 100 N, applied to it. The handle is free to move.

    What is the effect of the forces on the handle?     Imagen de la pregunta 9
    1. AA The handle will move downwards.
    2. BB The handle will not move.
    3. CC The handle will turn anticlockwise (to the left).
    4. DD The handle will turn clockwise (to the right).
  10. 10The engine of a car produces a driving force of 5000 N on the car. Resistive forces R also act on the car, as shown.
    The car has a mass of 800 kg and an acceleration of 1.0 m/s^2.

    What is the value of R?     Imagen de la pregunta 10
    1. AA 800 N
    2. BB 4200 N
    3. CC 5800 N
    4. DD 8000 N
