Subject: Why Should we pull the weight " Slightly " in SHM?

Why Should we pull the weight " Slightly "
經過幾次無聊try
扯勁d 同slight , oscillate 5 次個period 一樣
但oscillate 次數愈多...個string 會左搖右擺 (NOT Vertical motion only)
咁period 就同slightly時有出入

當扯得好勁,放手
咁個weight 彈上去最盡便不再做SHM.. (large compression in the string)
and then back to eq. point

So... WHY should we pull the weight " Slightly"
係關compression in the string,affect our result 還是若不slightly,
oscillate時左右搖擺afftect our result..!? and HOW to affect !?
( NOT VERTICAL MOTION ONLY )

thx
