2.如图1所示,表面粗糙的固定斜面顶端安有滑轮,两物块P、Q用轻绳连接并跨过滑轮(不计滑轮的质量和摩擦),P悬于空中,Q放在斜面上,均处于静止状态。当用水平向左的恒力推Q时,P、Q仍静止不动,则

    A.Q收到的摩擦力一定变小,地面对斜面

的支持力也变小。

    B.Q受到的摩擦力一定变大,地面

对斜面的摩擦力由0变为不为0                    图1

    C.轻绳上的拉力一定变小,Q收到的支持力变大

    D.轻绳上的拉力一定不变,地面的支持力不变

1.下列说法中正确的是:

    A.有摩擦力就有弹力,摩擦力不能成为动力,但可以成为向心力

    B.当作用力做正功时,反作用力也可能是做的正功,一对静摩擦力所做总功一定为零

    C.物体的加速度越大,运动就越快,物体所受合力越大,运动也越快

    D.质量越大的物体惯性越大,速度越大的物体越不易停下来,所以惯性也越大
