Q1Mass, Weight and DensityPhysical Quantities and MeasurementForcesFree sample

The apparatus shown in Fig. 1.1 is used to measure the extension of a spring.

Fig. 1.1

(a)

Explain how the mass causes a force on the spring.

(b)

The force on the spring is a vector quantity. State what is meant by a vector quantity.

(c)

Fig. 1.2 shows a graph of the length of the spring plotted against the force on the spring, for forces between $0$ and $10\text{ N}$ .

Fig. 1.2

(i)

(1)

State a formula that relates the unstretched length $l_0$ of the spring, the stretched length $l$ of the spring and the extension $e$ of the spring.

(2)

A mass produces a force of $9.0\text{ N}$ on the spring. Determine the extension of the spring caused by this mass.

extension = ______

(ii)

The limit of proportionality of the spring is reached when the force is $10\text{ N}$ .

The spring is easier to stretch after the limit of proportionality.

On Fig. 1.2, continue the line to suggest how the length changes when the force is greater than $10\text{ N}$ .
