physics

Focus on the simple pendulum investigation and helical spring investigation :

• Research question

• Hypothesis

• Independent, dependent and controlled variables

• Materials

• Method

• Safety precautions

• Collecting sufficient and reliable data

Revise how to:

• Calculate average time

• Calculate period T

• Calculate T2

• Plot and interpret graphs

• Describe relationships in data

• Evaluate a hypothesis

• Identify errors

• Suggest improvements to the method
