OUTCOME
By the end of this lesson you will be able to recognise and use a field distance graph to describe an electric field and it effect on a test charge. You will be able to determine the work done by a field on a test charge in a uniform electric field.
The definition of the uniform electric field, the forces on charged objects in uniform fields and the work done (energy) in moving charges through uniform fields.
LEARNING TASKS
Explain
1. How do you find the work done on a charge in an electric field given the Force distance graph?
2. What is a uniform electric field?
What are the similarities between a charge moving in an electric field and a mass moving in a gravitational field?
Explore and Elaborate
Cyclotrons and other accelerators use electric fields to move charged particles. In the activity below you will make your worn ball cyclotron.
