Results

• 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.

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.

This YouTube video introduces you to the basics of decimals.

This video explores how decimals are represented on the number line.

Outcomes
