This video explains the angles of elevation and depression.

• 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.

The two YouTube videos provide an indication of the differences in dairy farming between Tanzania and South Australia.

• The first YouTube video elaborates on a few of the achievements that resulted from the implementation of the Tanzania livestock master plan between 2017/18 - 2021/22
• The second YouTube video provides some insight into the dairy industry in South Australia

• Relate the electrostatic force magnitude to the charges and the distance between them
• Explain Newton's third law for electrostatic forces
• Use measurements to determine Coulomb’s constant
• Determine what makes a force attractive or repulsive

This YouTube video delves into the impact that tourism can have on a country's economy.

This YouTube video delves into the impact that tourism can have on the environment.

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.

• Predict, qualitatively, how an external force will affect the speed and direction of an object's motion.
• Explain the effects with the help of a free body diagram.
• Use free body diagrams to draw position, velocity, acceleration and force graphs and vice versa.
• Explain how the graphs relate to one another.
• Given a scenario or a graph, sketch all four graphs.
