Show the answer and mark scheme
2(a)(i)[2]
magnitude or size
direction
2(a)(ii)[2]
any two from:
acceleration / deceleration, gravitational field strength, impulse, momentum, velocity, weight
2(b)(i)[1]
0.12 m
2(b)(ii)[2]
beyond where the extension is not directly proportional to the load or (point) where extension stops being directly proportional to the load or point up to which extension is directly proportional to the load
10.4 N ⩽ weight ⩽ 10.9 N
2(b)(iii)[3]
22 N / m ⩽ k ⩽ 25 N / m
clear subtraction of 0.12 from a length that is in Hooke’s law region
e.g. 0.54 – 0.12
k = F / x in any form or k = W / x in any form or k = 1 / gradient
