    Question 3
    HLPaper 1

    What is friction?

    I. A force that acts parallel to two surfaces in contact
    II. A force that opposes relative motion
    III. A force that acts through the centre of mass

    Question 4

    Question 5
    HLPaper 1

    Which action would decrease the coefficient of friction?

    Question 6
    HLPaper 1

    Why is maintaining a steady speed in canoeing less challenging than initiating movement from a standstill?

    HLPaper 1

    Which of the following factors most significantly influences the amount of drag experienced by a swimmer?

    Question 8
    HLPaper 2

    An alpine skier is descending a steep slope. The diagram below shows the forces acting on the skier during the descent.

    1.

    Identify the forces acting on the skier as shown in the diagram.

    Explain how friction affects the skier's performance during the descent.

    [3]
    3.

    Calculate the net force acting on the skier if the gravitational force component along the slope is 600 N, the normal force is 400 N, the frictional force is 150 N, and the drag force is 100 N.

    [2]
    4.

    Discuss how the skier can optimize their performance by managing friction and drag forces.
