原声例句
可汗学院:物理 Well, it would be the force of friction. 应该是摩擦力。 可汗学院:物理 8m is the force of friction. 8m是摩擦力。 可汗学院:物理 So we would have a force of friction acting upwards. 所以应该有一个向上的摩擦力 对吧? 可汗学院:物理 This is the force of friction or you can call it air resistance. 现在考虑更多的例子。 可汗学院:物理 But then there's a force of friction between the rock and the ground that is going 2... 现在考虑更多的例子。 可汗学院:物理 So that right over there is the force of friction. It's going against that guy's pushing. 现在考虑更多的例子。 可汗学院:物理 There is not just the force of me pushing. There is also the force of friction. 实际上, 物体所受的力不单只是推力, 还有摩擦力。 可汗学院:物理 This right over here is the force of friction. 这一节和上一节的差异在于 上次摩擦力是静态的。 可汗学院:物理 And as you can imagine, this is the force of friction. 这个力是摩擦力。 可汗学院:物理 I could have if I had a force of friction. 如果我有摩擦力, 我就能做到。 可汗学院:物理 I'm gonna have a force of friction that I have to subtract. 我将有一个必须减去的摩擦力。 可汗学院:物理 If my force of pushing is less than the force of friction, then the TV set will to decelerate. 如果推力小於摩擦力, 则电视会慢下来。 可汗学院:物理 So minus mu K so the force of friction--- I'll just put force of friction. 所以减去 mu K 所以摩擦力 --- 我只输入摩擦力。 可汗学院:物理 If my force of pushing is larger than the force of friction, then my TV set will accelerate. 如果推力大於摩擦力, 电视将会加速运动. 可汗学院:物理 29.4 Newtons minus the force of friction it's given by. So there's a formula for force of friction. 29.4 牛顿减去它给出的摩擦力。所以有一个摩擦力的公式。 可汗学院:物理 The force of friction is always mu K FN. 摩擦力始终为 mu K FN。 少儿科学秀 The force of friction pushes hard against your socks as you try to slide them across the carpet. 当您试图将袜子滑过地毯时,摩擦力会强烈地挤压您的袜子。 可汗学院:物理 This guy's pushing harder with 3 N, but the force of friction is now 2 N to the left. 现在考虑更多的例子。 可汗学院:物理 It's only the normal force on this five kilogram mass that's contributing to this force of friction here. 只有作用在这个 5 千克重物上的法向力才对此处的摩擦力产生影响。 玩转物理学 And the force of friction does not depend on the size of the surface area of contact between the two surfaces. 并且摩擦力不取决于两个表面之间接触表面积的大小。 |
