B2. Developing Skills of Investigation and Communication
B2.1 use appropriate terminology related to dynamics, including, but not limited to: inertial and non-inertial frames of reference, components, centripetal, period, frequency, static friction, and kinetic friction
B2.2 solve problems related to motion, including projectile and relative motion, by adding and subtracting two-dimensional vector quantities, using vector diagrams, vector components, and algebraic methods
B2.3 analyse, in qualitative and quantitative
terms, the relationships between the force of gravity, normal force, applied force, force of friction, coefficient of static friction, and coefficient of kinetic friction, and solve related two-dimensional problems using free-body diagrams, vector components, and algebraic equations B2.4 predict, in qualitative and quantitative
terms, the forces acting on systems of objects (e.g., masses in a vertical pulley system [a “dumb waiter”], a block sliding off an accelerating vehicle, masses in an inclined-plane pulley system), and plan and conduct an inquiry to test their predictions B2.5 analyse, in qualitative and quantitative
terms, the relationships between the motion of a system and the forces involved (e.g., a block sliding on an inclined plane, acceleration of a pulley system), and use free-body diagrams and algebraic equations to solve related problems B2.6 analyse, in qualitative and quantitative
terms, the forces acting on and the acceleration experienced by an object in uniform circular motion in horizontal and vertical planes, and use free-body diagrams and algebraic equations to solve related problems B2.7 conduct inquiries into the uniform circular
motion of an object (e.g., using video analysis of an amusement park ride, measuring the forces and period of a tether ball), and analyse, in qualitative and quantitative terms, the relationships between centripetal acceleration, centripetal force, radius of orbit, period, frequency, mass, and speed |
B3. Understanding Basic Concepts
B3.1 distinguish between reference systems
(inertial and non-inertial) with respect to the real and apparent forces acting within such systems (e.g., apparent force in a rotating frame,apparent gravitational force in a vertically accelerating frame, real force pulling on the elastic of a ball-and-paddle toy) B3.2 explain the advantages and disadvantages of static and kinetic friction in situations involving various planes (e.g., a horizontal plane, a variety of inclined planes)
B3.3 explain the derivation of equations for uniform circular motion that involve the variables frequency, period, radius speed, and mass
