Paper 1 H - SAMPLE SET 1 Q20
20) A student investigates the motion of a glider on a frictionless air track using the apparatus shown
in the picture.
(a) (i) Explain how the student can use this apparatus to demonstrate Newton’s Second Law.
Include details of any additional equipment required. [3]
(ii) A 0.25 kg glider is pulled by a 1.0 N force.
Calculate the acceleration of the glider using the formula: [1]

(ii) A 0.25 kg glider is pulled by a 1.0 N force.
Calculate the acceleration of the glider using the formula: [1]
force = mass x acceleration
answer: ........................... m/s2
(iii) Suggest reasons why the recorded value was less than your calculated value. [2]
(b) The student repeats the experiment for 4 more forces.
There is an anomaly in the results.
Identify the anomaly and explain how the student could have dealt with it. [2]
(c) Explain what is meant by a reproducible experiment. [1]
(Total for Question 20 = 9 marks)
