Figuring out the acceleration of ice down a plane made of ice.

Basic primer on Newton's First Law of motion.

• Predict how current will change when resistance of the circuit is fixed and voltage is varied.
• Predict how current will change when voltage of the circuit is fixed and resistance is varied.

This is a short tutorial on how to define and measure the perimeter of shapes

By the end of this course you will be able to:

1. Define the terms perimeter and area
2. Find the perimeter of any polygon
3. Find the perimeter and area of a trapezium, parallelogram, rectangle and square
4. Find the area of a triangle
5. Find the perimeter and area of a circle

Electrical devices convert the electrical energy carried by the charges into other types of energy such as heat, sound, and motion. Components in the appliance resist the flow of charge and are referred to as resistors. In this unit1 you will understand what resistance is, the factors that affect the resistance and the relationship between resistance and current.
