ADVICE FOR PARENTS · GCSE Physics support
Helping your child make sense of GCSE Physics
A Physics equation is easier to use when the student knows what its quantities mean. If your child can recite a formula but is not sure where to start, connect the symbols to one simple situation before adding more calculation.
A guide from Tutoring with Maurice
Ask Maurice about one-to-one online tutoring →The starting point: First ask what is happening, what is given and what needs to be found. Then choose the equation and check the units.
A PRACTICAL TAKEAWAY
Try this: explain an average-speed calculation
Use a short example in which the distance and time are already in metres and seconds.
- A cyclist travels 100 metres in 20 seconds. Ask: “What does average speed tell us?” It describes the total distance travelled per unit of time over the journey.
- Write average speed = total distance ÷ total time. Calculate 100 ÷ 20 = 5 m/s. The units mean metres per second.
- Ask: “Does 5 m/s mean the cyclist travelled at exactly 5 m/s all the time?” No: it is the average for the whole journey; the speed may have changed.
Translate the question before calculating
Ask the student to describe the situation in ordinary words. What object or system is involved? What changes? What quantity are they being asked to find? A labelled sketch can help organise the information.
Write the known quantities with their units, then choose a relationship that connects them to the unknown. For density, for example, mass and volume have different jobs: density = mass ÷ volume. Increasing either quantity does not have the same effect.
In the density and pressure tool, students can change a block’s mass or volume and compare what happens. Ask them to predict the result before reading it.
Use units to keep track of the meaning
Units are part of the calculation. A question might give time in minutes while an equation needs seconds, or a length in centimetres while a calculation uses metres. Write the conversion before substituting values.
For example, 2 minutes = 120 seconds. Travelling 600 metres in that time gives an average speed of 600 ÷ 120 = 5 m/s. Dividing by 2 instead would give 300 metres per minute, which is a different unit.
The units lesson and rearranging formulae lesson can support these steps. Begin with the simple activity before using a GCSE extension.
Ask what a diagram or animation is showing
Do more than watch an animation. Ask the student to predict one change, use a control, then explain what happened in their own words. In the heating tool, warmer liquid particles move faster on average; the particles themselves do not grow.
A model highlights an idea while leaving out some real-world detail. Read the tool’s notes about its assumptions and simplifications. A Physics explanation also needs words: a correct calculation alone does not explain why something happens.
Try questions such as “Which quantity did we keep the same?” or “What evidence in the picture supports your explanation?” If the student is unsure, return to one change rather than adding several controls at once.
Match support to the student’s Physics course
Tell Maurice which GCSE science qualification your child is taking, if you know it, and bring any teacher feedback. The school’s exam-board specification is the guide to the exact content and assessment requirements. The lab covers selected ideas rather than the full course.
Maurice is a retired professional engineer and STEM Ambassador with over 9 years of tutoring experience. His GCSE Physics support connects theory to practical examples and can include topic work and past-paper questions on Zoom.
His free first assessment includes parent and student. GCSE Higher lessons are £30 per hour, with discounts available for 10 or more sessions. Ask for the Foundation price, current availability and which support fits the course.
