Figure 1 The weight of the person causes the spring to extend. 0 1 . 1 Why does the weight of the person cause the spring to extend? [1 mark] Tick () one box. Weight acts downwards Weight acts in all directions Weight acts upwards Do not write outside the box *02* IB/M/Jun23/8464/P/2F 3 0 1 . 2 Complete the sentence. Choose the answer from the box. [1 mark] a gravitational a frictional an electrostatic The weight of the person in Figure 1 is force. Question 1 continues on the next page Do not write outside the box *03* Turn over ► IB/M/Jun23/8464/P/2F 4 The weight of the person causes an extension in the spring of 0.070 m. The spring constant of the spring is 12 000 N/m. 0 1 . 3 Calculate the weight of the person. Use the equation: weight = spring constant × extension [2 marks] Weight = N 0 1 . 4 Calculate the elastic potential energy stored in the extended spring. Use the equation: elastic potential energy = 0.5 × spring constant × (extension)2 [2 marks] Elastic potential energy = J Do not write outside the box *04* IB/M/Jun23/8464/P/2F 5 0 1 . 5 If there is more than one person on the chair, the spring could become inelastically deformed. What is meant by ‘inelastically deformed’? [1 mark] Tick () one box. The spring extends more when two or more forces act on it. The spring will not go back to its original length when the force is removed. The spring extends so that it is twice as long as its original length. Question 1 continues on the next page Do not write outside the box *05* Turn over ► IB/M/Jun23/8464/P/2F 6 The manufacturer of the chair investigated the extension of a new spring. 0 1 . 6 Figure 2 shows slotted masses hanging from the spring. The weight of the masses extends the spring.
