You need to understand the WAEC GCE Physics Practical marking scheme before attempting any question so as to present your answers in such a way that it will look attractive to the examiner to earn you big marks.

Bear in mind that every single procedure is awarded marks. So, ensure you do not skip any step while reporting and presenting your alternative to practical results. And do not forget to remember that the units are very important.

The Physics Practical question paper will consist of three areas and general Physics questions namely:

  1. Optics
  2. Electricity
  3. Mechanics

You will be expected to take your readings from an alternative to practical experiment, take readings and tabulate your values, plot graph, state precautions to be taken during the experiment, and report observation.

What you will see will not be far from the WAEC Physics Specimen given to your school.

Note: Ensure you avoid parallax error while taking your readings to get accurate results and do not forget to choose lines of best fit while plotting the graph. It is not compulsory that all the points will enter the line.

Practice questions

1(a)

You are provided with two retort stands, two metre rules, pieces of thread and other necessary apparatus. (i) Set up the apparatus as illustrated above ensuring that the strings are permanently 10cm from either end of the rule.

(ii) Measure and record the length L = 80cm of the two strings.

(iii) Hold ends of the rule and displaces the rule slightly, then release so that it oscillates about a vertical axis through its centre.

(iv) Determine and record the time t for 10 complete oscillations. (v) Determine the period T of oscillations.

(vi) Evaluate log T and log L. (vii) Repeat the procedure for four other values of L = 70cm, 60cm, 50cm, and 40cm.

(viii) Tabulate your readings.

(ix) Plot a graph with log T on the vertical axis and log L on the horizontal axis.

(x) Determine the slope, s and the intercept, e on the vertical axis, of the graph.

(xi) State two precautions taken to ensure accurate results.

(b)(i) Define simple harmonic motion

(ii) Determine the value of L corresponding to t = 12s from the graph in 1 (a).
