Oscillations

Question 1

Explain how ductile material damp oscillations

Answer 1

Ductile - A material that can be plastically deformed without fracture - which means that it can absorb a lot of energy. Material is plastically deformed so energy removed from system

Question 2

Give the equation for the time period of a mass on a spring

Answer 2

T = 2pi * sqrt(m/k)

Question 3

Give the equation for the time period of a pendulum

Answer 3

T = 2pi * sqrt(l/g)

Question 4

Draw the displacement/time, velocity/time and acceleration/time graphs for SHM

Answer 4
