AQA GCSE · Question 03.2.2 · Forces

Which of these is the dependent variable?

Answer options:

A.

Acceleration of the trolley

B.

Length of the bench

C.

Total mass of the trolley

D.

Force pulling on the trolley

How to approach this question

The dependent variable is the one that is *measured* to see the effect of the change made to the independent variable. Read the description of the experiment to identify which variable was measured.

Full Answer

A.Acceleration of the trolley✓ Correct
Acceleration of the trolley
In a scientific investigation: - The **independent variable** is the one you change. The description says "different masses were put on the trolley". - The **dependent variable** is the one you measure. The description says "the acceleration of the trolley was measured". - **Control variables** are the ones you keep the same. The description says "The force was then kept constant". Therefore, the acceleration of the trolley is the dependent variable.

Common mistakes

✗ Confusing independent and dependent variables. The dependent variable *depends* on the independent one.
