一道英语的物理题目,貌似很简单的~~
as shown, a object starts from rest and moves down a slope(斜面), ignoring friction(摩擦). please calculate the power of Gravity(重力) at the moment when the object has tyved a distance of 15m. the angle q of slope is 37°. the power of Gravity here is_______________.____________
谢拉...
顺便问一下the power of Gravity是重力做的功吗?
