What is the acceleration due to gravity at the space station.

Solving a word problem to find average velocity and speed of an object 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.

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

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

When electromagnetic radiation is absorbed by a material the energy it carries has to go somewhere. When lower energy waves, like radio and infrared waves, are absorbed there can be an increase in temperature of the absorbing material. Higher energy waves, like x-ray and gamma waves, can actually permanently damage or change materials. Learn about the different types of electromagnetic waves and how their energies can influence their effects on objects.

• Identify when forces are balanced vs unbalanced.
• Determine the sum of forces (net force) on an object with more than one force on it.
• Predict the motion of an object with zero net force.
• Predict the direction of motion given a combination of forces.
