You have two springs th2*jqsog):b ijnme4+,/3ktgm lc5 *8 stkkimd at are identical excepal+6hzkvty8 pm1 l.5;uk ny/ xt that spring l is stiffer than sprvulk n.l5my8p kh +6;z1x/ytaing 2 $(k_1>k_2).$ On which spring
is more work done $(a)$ if they are stretched using the same force, $(b)$ if they are stretched the same distance?
参考答案: $(a)$ In this case, the same force is applied to both springs. Spring 1 will stretch less, and so more work is done on spring 2. $(b)$ In this case, both springs are stretched the same distance. It takes more force to stretch spring 1, and so more work is done on spring 1.
