Question 4 NECO • 2025 • PHYSICS • practical

A spring is hung vertically and a set of masses is attached one at a time. The extensions of the spring are recorded as shown:

Question Parts

( a )

Using the data below, plot a graph of load (N) against extension (m). From the graph, determine the spring constant k (N m⁻¹) by calculating the gradient using the two extreme points.

( b )

If an unknown object caused the spring to extend by 8.5 cm, calculate the mass of the object using the spring constant obtained in part (a).

( c )

Explain why the load‑extension graph should ideally pass through the origin and what a significant deviation from the origin would indicate about the spring.

( d )

State two precautions that should be observed when performing this experiment.
