Calculating Gravitational Potential Energy

Forces at a distance are explained by fields (gravitational, electric, and magnetic) permeating space that can transfer energy through space. Magnets or electric currents cause magnetic fields; electric charges or changing magnetic fields cause electric fields.

Calculating height using energy

Learn how you can calculate the maximum height of a launched object by using the total energy of a system. Energy that is conserved can be transferred within a system from one object to another changing the characteristics of each object, like position.

Calculating kinetic energy

Mathematical expressions, which quantify how the stored energy in a system depends on its configuration (e.g. relative positions of charged particles, compression of a spring) and how kinetic energy depends on mass and speed, allow the concept of conservation of energy to be used to predict and describe system behaviour.

Calculations on motion in one dimension

In this unit you will apply your understanding of the components of motion in one dimension using linear equations. This will help you to solve problems about motion in one direction and equip you to understand how these concepts apply to everyday life.

There are three equations for linear motion with constant acceleration. They can be used to calculate, and therefore predict, the outcome of motion when three out of the four variables are known.

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.
