Applications of SHM

Question 1

What is the equation for force exerted on spring? and accelertaiton

Answer 1

restoring force / mass = -kx / m

Question 2

How is SHm investigation using a mass-spring system?

Answer 2

• use small spring
• use 100g and 50g masses
• load up to 400g in intervals of 400g
• stopwatch to time
• use position sensor to measure displacement over time
• connect to computer to create a displacement time graph
• or
  
  • measure period of 5 oscillation and divide

Question 3

Which factors can be changed that affect period?

Answer 3

• mass
• stiffness constant
• amplitude

Question 4

How can pendulum be investigated?

Answer 4

• attach pendulum to angle sensor
• displace pendulum from rest position of small angle
• angle sensors measures displacement
• read period
• or measure 5 oscillation and divide by 5
• could change​
  
  • to see how they effect period
  • length of rod
    
    • increeases
  • mass
    
    • stays same
  • amplitude
    
    • no effect
