Investigation into SHM using a mass-spring system and a simple pendulum

Question 1

what spring is used

Answer 1

• 20mm
• expendable
• try not to stretch past elastic limit

Question 2

spring experiment

Answer 2

• attach different masses
  
  • up to 100g
• pull masses down a set amount
  
  • initial amplitde
• now oscillates with SHM
• position sensor measurs displace of the mass over time
• coneect the possition sensor to computer to create a displacement0time grtaph
• read off the the period T from the graph
