What is the glossary of key Physics verbs?

This ‘glossary of key physics verbs’ is a list of the definitions of commonly used verbs that appear frequently in the NESA syllabus, performance descriptions and examinations.

The purpose behind this glossary is to help students answer Physics exam questions effectively. Each verb includes sample questions to provide context of how it’s used in the Physics course.

Go to Physics verb:

Account for

State reasons for, report on.

Module 8 Question (2 Marks)
Account for the distribution of energies in a beta decay curve.

Analyse

Identify components and the relationship between them; draw out and relate implications.

Module 8 Question (6 Marks)
Using the standard model, analyse the roles of both forces and particles in the current understanding of the atom.

Apply

Use, utilise, employ in a particular situation.

Assess

Make a judgement of value, quality, outcomes, results or size.

Module 5 Question (5 Marks)

A student wishes to repeat some of Galileo’s experiments on projectile motion. He set up a ramp on a table of height H and rolled a ball down the ramp, such that it rolled horizontally off the table. When he released the ball from a height h1 up the ramp, the ball landed a distance x1 from the edge of the table.

In Galileo’s experiments, he released the ball from different heights on the ramp. The student was not familiar with the result and predicted that:

Releasing the ball from higher up the ramp will make it land on the floor further away from the table. Hence, it will take more time to reach the floor once it leaves the table.”

Assess the accuracy of this prediction.
