When the ball on a spring is replaced by a smaller ball with half the mass : The period decrease by 29%
<h3>Calculate the Period </h3>
We will apply the formula below to calculate period
T =
where :
T₁ / T₂ = where m₂ = m₁ / 2
Therefore :
T₂ = = 0.71 T
Hence we can conclude that the period will decrease by 29% ( i.e 100 - 71 ).
