首先由第一题的结论可以知道滑动的盒子在底端的速度最快,因为潜在能量损失( MgH )完全转化为盒子的平动动能。 速度最快可以推导出下落时间最快吗?答案是可以的,试想在每下落一个极小的斜面,滑动的盒子速度都大于另外几个滚动的东西,所以最后下落的时间一定是最少的。 对于滚动的来说,列方程 MgH=\frac12Mv^2...

Physics Rotational Motion and Angular Momentum Search for: Kinematics of Rotational MotionLearning Objectives By the end of this section, you will be able to: Observe the kinematics of rotational motion. Derive rotational kinematic equations. Evaluate problem solving strategies for rotational kinematics....
An object can be rotating while also experiencing linear motion; just consider a football spinning like a top as it also arcs through the air, or a wheel rolling down the street. Scientists consider these kinds of motion separately because separate equations (but again, tightly analogous) are ...
4. A soccer player extends her lower leg in a kicking motion by exerting a force with the muscle above the knee in the front of her leg. She produces an angular acceleration of 30.00 rad/s2and her lower leg has a moment of inertia of0.750kg⋅m20.750kg⋅m2What is ...

II.C Equations of Motion In translational motion, the driving force F is counterbalanced by a resisting force Fr set up by the driven machine and by an inertia force Ma arising from the change in speed, or (2)F−Fr=Ma=Mdυ/dt, where the mass M is expressed in kg. the velocity v...
Physics Lab#3 : Torque & Rotational Equilibrium Intro: Similar to the fact that a force is anything that can cause a linear acceleration, a torque occurs by any force that is able to cause an angular acceleration. Static torque exists when the syst...
