Key ideas

  1. An investigable question can be answered by observation or measurement.

  2. A scientific milestone can overturn how a community understands nature.

  3. Good physics questions often arise from everyday motion, forces, and waves.

  4. New evidence or ideas can force a rethinking of accepted theory.

  5. A clear question names the variables that could be measured.

Watch out for

  • Thinking any question is investigable - it must be testable by observation or measurement.
  • Thinking scientific ideas never change - milestones can revolutionize them.
  • Asking a question so vague no variable can be measured.

Unit 2 · 3 skills

Kinematics

Describing Motion with Vectors

The official wording · 3 outcomes
2.1
identify the frame of reference for a given motion
2.2
use vectors to represent position, displacement, velocity, acceleration, and force
2.3
analyse graphically and mathematically the relationships among displacement, velocity, and time

Key ideas

  1. A frame of reference is the viewpoint from which motion is measured.

  2. Whether an object is moving depends on the chosen frame.

  3. Motion described in one frame can look different in another.

  4. A frame is defined by an origin and a direction.

  5. A vector has both magnitude and direction; a scalar has only magnitude.

Watch out for

  • Thinking motion is absolute - it is always relative to a frame.
  • Forgetting to state the frame when describing motion.
  • Confusing distance (scalar) with displacement (vector).

Unit 3 · 1 skill

Dynamics

Newton's Laws of Motion

The official wording · 1 outcomes
3.1
apply Newton’s laws of motion to explain inertia; the relationship among force, mass, and acceleration; and the interaction of forces between two objects

Key ideas

  1. Newton's first law (inertia): an object stays at rest or in uniform motion unless a net force acts.

  2. Newton's second law: net force equals mass times acceleration (F = ma).

  3. Newton's third law: for every action there is an equal and opposite reaction.

  4. A net (unbalanced) force is required to change an object's motion.

Watch out for

  • Thinking a moving object needs a continuous force to keep moving - it only needs one to change its motion.
  • Thinking action-reaction forces cancel on the same object - they act on different objects.

Unit 4 · 9 skills

Momentum and Energy

Momentum and Its Conservation

Work, Power, and Energy

The official wording · 9 outcomes
4.1
apply quantitatively the laws of conservation of momentum to one-dimensional collisions and explosions
4.2
analyse quantitatively the relationships among force, displacement, and work
4.3
analyse quantitatively the relationships among work, time, and power
4.4

4.5

4.6

4.7
analyse common energy transformation situations using the work-energy theorem
4.8
determine which laws of conservation of energy or momentum are best used to solve particular real-life situations involving elastic and inelastic collisions
4.9
determine the percent efficiency of energy transformations

Key ideas

  1. Momentum is mass times velocity (p = mv), a vector quantity.

  2. Work is done when a force moves an object through a displacement.

  3. In an isolated system, total momentum is conserved.

  4. Work equals force times displacement in the direction of the force (W = Fd).

  5. Total momentum before a collision equals total momentum after.

Watch out for

  • Thinking momentum is not a vector - direction matters.
  • Thinking any effort is work - work needs displacement in the force's direction.
  • Thinking momentum is conserved only in elastic collisions - it is conserved in all collisions in an isolated system.

Waves

Wave Properties and the Wave Equation

Wave Phenomena, Sound, and Radiation

  • Interference, diffraction, and the Doppler effect

    I can explain wave interference, diffraction, and the Doppler effect.

  • Comparing sound and electromagnetic radiation

    I can compare the properties of sound and electromagnetic radiation.

  • How sound and radiation are produced and transmitted

    I can describe how sound and electromagnetic radiation are produced and transmitted.

The official wording · 6 outcomes
5.1

5.2

5.3
apply the laws of reflection and the laws of refraction to predict wave behaviour
5.4

5.5
compare and describe the properties of electromagnetic radiation and sound
5.6
describe how sound and electromagnetic radiation, as forms of energy, are produced and transmitted

Key ideas

  1. A wave transfers energy without transferring matter.

  2. Interference is the combining of overlapping waves into larger (constructive) or smaller (destructive) amplitudes.

  3. In a transverse wave, the medium moves perpendicular to the wave's direction.

  4. Diffraction is the spreading of a wave as it passes an edge or through a gap.

  5. In a longitudinal wave, the medium moves parallel to the wave's direction (compressions and rarefactions).

Watch out for

  • Thinking a wave carries matter along with it - it carries energy.
  • Thinking interference destroys energy - it redistributes it.
  • Confusing transverse and longitudinal motion of the medium.
