A person is pushing a box up an inclined plane. The force applied is parallel to the incline. If the weight of the box is 100 N and the incline angle is 30 degrees, what is the component of the weight parallel to the incline?
A block is sliding down an inclined plane. The force that is parallel to the plane and causes the block to move is: A. Normal force B. Friction force C. Gravity force D. Applied force 相关知识点: 试题来源: 解析 C。使物体沿斜面下滑的力是重力沿斜面的分力,选择 C。A 选项法向力垂直于...
equal to the component of gravity along the plane D. less than the component of gravity along the plane 相关知识点: 试题来源: 解析 C。本题考查在斜面上物体受力平衡的分析。当物体匀速上滑时,沿斜面向上的拉力等于重力沿斜面的分力。易错点是容易忽略拉力与重力分力的关系。解题关键是正确分析力的分解...
The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body’s state of rest or motion. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force, an...
