IB SEHS - Topic 4: MOVEMENT ANALYSIS EXAM

1 - Which law states "for every action there is an equal and opposite reaction"?

• Newton's 1st law
• Newton's 2nd law
• Newton's 3rd law
• law of conservation of momentum

2 - the diagram below demonstrates an athlete performing a leg press. Which correctly identifies the fulcrum, effort, and load for this lever?

• X = FULCRUM, Y = EFFORT, Z = LOAD
• X = FULCRUM, Y = LOAD, Z = EFFORT
• X = LOAD, Y = EFFORT, Z = FULCRUM
• X = LOAD, Y = FULCRUM, Z = EFFORT

3 - What type of lever is shown?

• First Class
• Second Class
• Third Class

4 - What type of lever is shown?

• First Class
• Second Class
• Third Class

5 - What type of lever is shown?

• First Class
• Second Class
• Third Class

6 - What does 'impulse' mean?

• the rate of change of velocity
• a force that acts in opposite to the movement of one surface on another
• the force applied over a given amount of time
• the speed of an object in a given direction

7 - Which of the following are vector quantities? I. momentum II. Force III. Velocity IV. Speed

• I and II
• I, II and III
• II and III
• I, III and IV

8 - Which statement best describes Newton's second law of motion?

• an object on which no net forces are acting has no change in velocity
• the rate of change of acceleration of an object is proportional to the force applied and acts in the driection of the force
• for every action there is an equal and opposite reaction
• an object will remain stationary or will move at a constant velocity or in a straight line

9 - What is the type of lever AND the movement taking place at the ankle joint when a gymnast points their toe and raises her center of gravity ?

• first class, plantar flexion
• second class, dorsiflexion
• third class, plantar flexion
• second class, plantar flexion
• first class, dorsiflexion

• Newtons 1st law
• Newtons 2nd law
• Newtons 3rd law
• more information is needed
