Mock exam paper A Higher Level Marking Scheme





General Guidelines

In considering this marking scheme the following points should be noted.

  1. In many instances only key words are given, words that must appear in the correct context in the candidate’s answer in order to merit the assigned marks.
  2. Marks shown in brackets represent marks awarded for partial answers as indicated in

the scheme.

  1. Words, expressions or statements separated by a solidus, /, are alternatives which are

equally acceptable.

  1. Answers that are separated by a double solidus, //, are answers which are mutually

exclusive. A partial answer from one side of the // may not be taken in conjunction with

a partial answer from the other side.

  1. The descriptions, methods and definitions in the scheme are not exhaustive and

alternative valid answers are acceptable. Marks for a description may be obtained from a relevant diagram, depending on the context.

  1. Where indicated, 1 mark is deducted for incorrect/ no units.
  2. Each time an arithmetical slip occurs in a calculation, one mark is deducted.
  3. The context and the manner in which the question is asked and the number of marks

assigned to the answer in the examination paper, determine the detail required in any

question. Therefore, in any instance, it may vary from year to year.

Higher level physics marking scheme


In an experiment to verify the principle of conservation of momentum, a body A was set in motion with a constant velocity. It was then allowed to collide with a second body B, which was initially at rest. After the collision both bodies moved off together with constant velocity. The following data was recorded during the experiment:

Mass of body A = 0.2kg

Mass of body B =0.18kg

Time taken for A to travel a distance of 20cm before the collision = 0.31s

Time taken for A and B to travel a distance of 20cm immediately after collision = 0.57s

Draw a diagram of the apparatus which was used in the experiment. ...
