Force, Mass & Acceleration II expands on the FMA relationship introduced in Level I using applied, practical and real examples. It details the expansion of Newton’s second law of motion and explains impulse and momentum and the relationship between the two. Vectors are examined and explanations are given for solving forces not acting along the same line.
The extension section is provided for students who are particularly interested in this topic area and wish to take the concepts further by moving from basic applications to those that are more complex, such as impulse and projectile motion.
Topics Covered:
Topics are related to 'working with forces and their effects' and are:
1. Applying force to an object
2. What is momentum? . A sporting application of momentum
3. What is impulse? . How does impulse relate to momentum? . Impulse and momentum applied to sport . Impulse - momentum relationship to improve performance and prevent injury . How does this relate to technique?
4. Force vectors and balanced forces . Adding and subtracting forces acting along the same direction . Solving for forces that are not acting along the same line . What is the graphical method to solve for these forces? . What is the mathematical method

Force, Mass and Acceleration II includes four interactive computer-based learning tools and focuses on the scientific application of mechanical principles to objects and bodies that are in motion. Students who are not familiar with mathematics and science-based subjects may find the concepts difficult to comprehend. The learning tools in this resource allow you to manipulate mechanical principles applied to real practical examples.
Learning Tool 1 allows students to solve vectors not acting along the same line. This tool can be used to reinforce the following concepts. · An object will generally continue to accelerate as long as the force is being applied. · Balanced and unbalanced forces. · Two forces that are in direct opposition to each other are subtracted from each other to produce the resultant or net force. · Solving for forces that are not acting along the same line.
Learning Tool 2 is divided into three parts and provides shot putt, golf and soccer examples to explain the impulse and momentum relationship. The unit can be broken down into an approach where the understanding of force is developed logically and applied to sporting examples and practical situations.
Part A is a detailed application of the concept of how a force is applied to an object that is to be projected into the air, using shot putt as the sporting example. It can be used to reinforce the following concepts. · Optimum conditions of force. · Optimum conditions of time of force application. · Force and time of force application acting on an object develops impulse. · Generally, the more impulse, the greater the velocity at release when throwing or kicking objects. · The more velocity at release, the greater the distance achieved (for a given angle of release and a specific direction).
Part B is a more detailed application of the concept of how a force is applied to an object that is to be projected into the air, this time using golf as the sporting example. It can be used to reinforce the following concepts. · Force and time of force application acting on an object develops impulse. · Generally, the more impulse, the greater the velocity at release. · The more velocity at release, the greater the distance achieved (for a given angle of release and a specific direction).
Part C is a realistic application of force, mass and acceleration, allowing the interactions to be applied to either soccer or golf. It can be used to reinforce the following concepts. · Optimum conditions of force, time of force application and angle of release. · Force and time of force application acting on an object develops impulse. · Generally, the more impulse, the greater the velocity at release. · The more velocity at release, the greater the distance achieved (for a given fixed angle of release and a specific direction) · Show that resultant force can be resolved into both horizontal and vertical components. · Show that the horizontal and vertical components of the resultant force produce the angle of force application. · Show that the force components are directly related to the velocity components.
