Charges and Fields

  • Determine the variables that affect the strength and direction of the electric field for a static arrangement of charges.
  • Investigate the variables that affect the strength of the electrostatic potential (voltage).
  • Explain equipotential lines and compare them to the electric field lines.
  • For an arrangement of static charges, predict the electric field lines. Verify the prediction using vector addition.

Force Diagrams

A force diagram is a useful tool to help us visualise forces acting on an object and gives us informa- tion about the object’s motion. We often use force diagrams when solving calculations involving the forces acting on an object.

Introduction to cellular respiration

Cellular respiration is the process by which cells derive energy from glucose. The chemical reaction for cellular respiration involves glucose and oxygen as inputs, and produces carbon dioxide, water, and energy (ATP) as outputs. There are three stages to cellular respiration: glycolysis, the Krebs cycle, and the electron transport chain.
