Explain, in terms of energy, why a pendulum swings lower and lowers when you let go of it

because of its energy store it had potential and gravity energy stores befoare you let it go and when it swings it lets off its gravitational enery and the potential energy goes to

Explanation:

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
