Unit Topic: Biomechanical Principles of Force and MomentumOverall aim of unit:The students will have a clear understanding of the biomechanical principles of force and momentum and be able to understand the principles of these terms when applied or mentioned in a sporting contextEquipment: IPads, Copies of the powerpoint, walls to push against, 30 cones, packet of sticky notes.Objectives for StudentsBy the end of the session students will understandForce is reported in the unit called Newtons (SI units) and is calculated by F=maThere are 2 categories of forces, contact and action at distance forces.Momentum is calculated by ‘mass x velocity’ and is measured in kg/m/sThere are 2 types of motion, linear (movement in a particular direction) and rotational (movement about an axis).Students will understand the key knowledgeNewton’s Laws of motion, including an understanding of force, mass and weight, acceleration and inertia applied to sport and physical activitiesThe principles of conservation and transfer of momentum, impulse and sequential and/or simultaneous force summation applied to sport and physical activitiesStudents will develop key skillsUse correct terminology to explain the application of biomechanical principles to a variety of sporting actionsPerform, observe, analyse and report on a variety of practical activities related to the application of biomechanical principlesCompare and contrast different sporting actions to identify the correct application of biomechanical principles to improve performance.(VCE Study Design, pg 14)Before Class students must complete the followingStudents can download the PowerPoint presentation from Blackboard.

The teacher will give a brief overview of the description the lessons objectives and ask the students their current knowledge of the subject.We will state some basic safety concerns due to the students participating in physical activity during the classInstructions:“Today the topic that we are focusing on is force and momentum. There will be practical as well as theory components to this lesson.”Objectives for the classTo learn and be able to apply the biomechanical concept of forceTo Learn and apply the biomechanical concept of momentumActivityActivity time: 4 minsInstruction time: 5 minsTotal time9 minsEquipment/areaSmart phones, walls to push against, Basketball court1958974-254000 20 m190507238900 15 mActivity on slide 628575113665001475105113665009912351289050051308012509500129730531750001070610323850078740031750005600703238500215265575945001968503238500210820850900002108202324100016421105759450016236953238500163766585090000163766523241000201866463500157035553975001098554191000787400131445001579880285750010414028575001584960254000123825317500 20 m190507238900 15 mLegend 190503619500 : students in pairs/groups19050-127000 : Teacher-31754953000 : Direction of pushingActivity 1: ForceActivity DescriptionWe will direct the student’s attention to the app iBooks which should have the power point presentation on it. The first part the students will need to look through is the information on force (slides 2 – 5). When the slides are finished, we will have the students perform the activities that are listed on slide 6. After the first activity on slide 6, students will be asked to watch the first listed video. They do the same with the second activity and video.ModificationsHave students in pairs and have them push back off the wall (relating to Newton’s 3rd law) while the partner stands behind and catches them.Safety considerationsMake sure there is space between groups pushingBe careful when pushing against someone else, don’t want anyone to fall on othersDemonstrationThe teacher will demonstrate the activity while pointing out the key points.Instructions:“We are beginning force by talking about Newtons 3 laws of motion. If you could open up the iBook app and open the powerpoint presentation.”Key teaching pointsThe law of inertia: an abject will remain at rest or in a uniform motion in a straight line unless acted upon by an unbalanced force.Force is reported in the unit called Newtons (SI units) and is calculated by F=maThere are 2 categories of forces, contact and action at distance forces.Focus questionsWhat are Newtons 3 laws of motion? Provide an example of each law.Why do you think gravitation force is both a contact and action at distance type of force?ActivityActivity time: 4 minsInstruction time: 5 minsTotal time9 minsEquipment/areaSmart phones, Basketball courtClass Layout1905014097000170815066040006858011461750042354566040004699060960000292106540500431808839200043180265430004235451111250094869065405004235451301750042354510922000 20m 15mActivity 1 on slide 121708150139700006102351397000088900013970000777875469900068580469900011010905080008890003746500610235374650088900010795000527685107950006115059080500889000908050061150513462000890270134620006858013462000 20m 15mActivity 2 on slide 129944101397000012306301397000017081501397000068580469900099441010541000245745508000123190013906500993140-5080001231900-44450084582045085006858013462000 20m 15mLegend190503619500 : students in pairs/groups19050-127000 : Teacher-31754953000 : Direction of jumping62865762000 : ConesActivity 2: MomentumActivity DescriptionThe students will be asked to look back at their smart phones/tablets and go through the powerpoint (slides 7 and 8).They will then watch the video on slide 8. The students will then continue and read slide 9 which will then be followed by a practical activity as explained at the bottom of slide 9. Students will continue and read through slide 10, watching the video at the end of the slide 10. Students will then move on and read introduction activity descriptor on slide 11Students will proceed to slide 12 to read and then perform the activities at the bottom of the slide upon discretion of the teacher. Appendix A is located on Slide 14 or a handout will be given by teacherSafety considerationsBe careful of other jumping when you areMake sure there is no one in your way (in front and behind) when jumpingMake sure you are not walking in front of others jumping/running up to jumpGroups must be a space clear of walls and other groups to avoid collision in running activityDemonstrationTeacher will demonstrate the activity, mentioning key points of the activity to be aware of.Instructions:“We are now moving onto momentum, and we will be looking at how momentum is calculated as well as how you can transfer momentum to have a positive effect.”Key Teaching PointsMomentum is calculated by ‘mass x velocity’ and is measured in kg/m/sThere are 2 types of motion, linear (movement in a particular direction) and rotational (movement about an axis).Transfer of momentum is simply transferring the weight from one object to another.Focus questions:Who has more momentum, a 80kg male running at 8km/h or a 60kg female running at 11km/h?What is the difference between linear and rotational motion? Give an example of each.ConclusionInstruction time and pack up3 minsTotal time3 minsEquipment/areaSmart phones, basketball courtClass Layout18199108509000180340116522500699135134620007239007816850071628035623500723900582295005092701346200053403578168500526415356235005340355822950037401558229500349250134620003740157816850036639535623500215265850900010617201587500 20m 15mConclusion:This will be a quick overview of what was covered in the class today as well as some focus questions for the student to further their understanding. (slide 13)The concluding focus QuestionsWhat did we learn about when you paired up and were pushing each other back to back? What type of force can this be put under?What was the difference between the 2 types of jumps? What is the reasoning behind this?ReferencesAFL.(2014).
