Your Learning Outcomes
• Define displacement, distance, average/instantaneous velocity and acceleration; choose a sign convention.
• Translate real‑world scenarios into kinematics variables and diagrams; set up 1D motion models.
• Apply kinematic equations to solve multi‑step problems.
• Analyze and construct x–t, v–t, and a–t graphs; use slope and area to move between representations.
• Model free‑fall with g; compare upward/downward motion; handle piecewise and relative motion in 1D.
• Build a systematic problem‑solving framework for planning, executing, and solving multi‑step problems.
• Work with 2D vectors in components; add/subtract vectors and understand angles and rotations.
• Solve projectile motion problems, including from different launch heights.
• Connect position-time, velocity-time, and acceleration-time graphs with two-dimennsional motion.
• Model 2D relative motion with velocity addition and reference frames.
• Apply relative motion strategies to solve multi-step problems in two dimensions
• Draw and interpret free‑body diagrams; identify system and surroundings.
• Apply Newton's Laws to relate net force, mass, and acceleration.
• Model common forces: weight, normal, tension, and friction (static/kinetic); analyze inclined planes.
• Analyze interacting objects and third‑law pairs; treat multiple‑object systems with internal/external forces.
• Solve equilibrium and accelerated‑motion problems in 1D/2D using components and (F=ma).
• Define angular position and angular displacement; work in radians with angular velocity.
• Connect linear and angular motion; relate speed, radius, and centripetal acceleration.
• Analyze uniform circular motion with free‑body diagrams; identify the centripetal direction and use period and frequency to connect motion with time.
• Model systems: conical pendulum, banked curves (with/without friction), and horizontal/vertical circles; evaluate apparent weight.
• Apply Newton’s Law of Universal Gravitation and understand the gravitational field; analyze circular orbits and Kepler’s third law.
• Define work using force and displacement; interpret the sign and units; connect area under the force‑versus‑position graph to work done.
• Distinguish kinetic, gravitational potential, and elastic potential energy; build energy bar charts and graphs for multi‑step situations.
• Apply the work–kinetic energy theorem to relate net work to changes in speed for motion on ramps and in circular paths.
• Use conservation of energy alongside work ideas to connect changes in kinetic and potential energy, understand how work by conservative forces relates to changes in potential energy, and track how non‑conservative forces add or remove energy from a system.
• Describe and calculate power as how quickly energy is transferred or transformed, and solve quantitative problems involving power and energy rates.
• Define linear momentum (p=mv); choose a sign convention and track direction for objects and systems.
• Classify multi‑object systems; isolated vs. non‑isolated, total momentum, and the link to center‑of‑mass velocity.
• Define impulse from average force and time; its direction matches the force.
• Use the impulse–momentum theorem; impulse is area under force‑time, force is slope of momentum‑time.
• Apply momentum conservation in 1D and 2D; separate internal vs. external forces; analyze collisions, recoil, and explosions.
• Classify collisions (perfectly inelastic, inelastic, elastic); pair momentum with kinetic energy to find final speeds and energy loss.
• Solve 2D collisions with component diagrams for unknown angles or speeds.
• Describe rigid rotation with rotational kinematics; connect (ω), (α), and tangential/centripetal terms.
• Define torque as (rFsinθ); use lever arm and sign conventions.
• Apply static equilibrium and Newton’s first law to bridges, ladders, and hinges.
• Compute moments of inertia and use the parallel axis theorem.
• Solve rotational dynamics with Newton’s second law, (Στ=Iα).
• Model no‑slip rolling and massive Atwood pulleys with coupled translation–rotation.
• Use torque, rotational work, and the work–kinetic energy theorem; interpret torque‑time graphs and relate them to angular impulse.
• Distinguish angular momentum of a particle vs an extended object; compare orbital and spin angular momentum and read angular momentum‑time graphs.
• Apply conservation of angular momentum and orbital conservation laws to interactions such as coaxial rotational collisions and orbital‑spin collisions.
• Analyze total kinetic energy of rigid systems and rolling with and without slipping.
• Connect universal gravitational potential energy to orbital motion and escape velocity.
• Define simple harmonic motion and identify systems that exhibit SHM.
• Relate period, frequency, and angular frequency for oscillating systems.
• Analyze the restoring force in springs using Hooke's law and connect it to SHM.
• Describe how displacement, velocity, and acceleration vary with time in SHM; interpret graphs of these quantities.
• Derive and apply the period of a mass‑spring system and a simple pendulum.
• Analyze energy transformations in oscillating systems; relate kinetic energy, potential energy, and total mechanical energy as a function of position.
• Define density and use it to compare materials.
• Define pressure as force per unit area; distinguish between absolute and gauge pressure.
• Apply Pascal's principle to analyze pressure transmission in enclosed fluids and hydraulic systems.
• Calculate how pressure varies with depth in a static fluid.
• Apply Archimedes' principle to determine buoyant force; analyze objects that float, sink, or are submerged.
• Use the continuity equation to relate fluid speed and cross‑sectional area in flowing fluids.
• Apply Bernoulli's equation to relate pressure, speed, and height in ideal fluid flow; use Torricelli's theorem, the Venturi effect, and other applications.
