Solving a word problem to find average velocity and speed of an object in one-dimension.

Patterns and processes of evolution. How evolution and natural selection are reflected in the similarities and differences of organisms. 

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.

• 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.

This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work. 

These videos look at how to compare decimals.

This online activity provides you with exercises on converting fractions to decimals.

• 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 course will explain what decimals are, how fractions can be expressed as decimals and how to convert fractions to decimals.
