Gelsonlab HSPD-068 Aparat za trčenje, nihajna kroglica, Newtonova zibelka Jeklena tehtnica Ball Physics Science Pendulum Desk
Odlična naprava za predstavitev Newtonovega tretjega zakona gibanja in načela ohranjanja zagona. Nova zasnova zagotavlja boljše rezultate, stabilnost in kakovost.Aparat za trčenje Newtownovih kroglic is one of the oldest, most interesting physics toys that demonstrate the laws of conservation of energy and momentum (and much more). You just raise one or two balls on one end, let them go and watch what happens on the other side. Great for physics demonstrations or as a desk toy/stress reducer, and makes a great gift.
