... I can describe the forces acting on an object undergoing horizontal rotational motion. Note: Forces acting on an object in vertical rotational motion are best analyzed using calculus, at an Honors but not Standard level. I can calculate torque given perpendicular force and lever arm. I can calculate ...

In the absence of friction, the car would continue to move with a constant velocity after the force was removed. The continued application of force w ...

... This is because no machine can perfectly transfer your input work to the output side of the machine. There is always some loss of energy as thermal energy. If you think about it, it kind of makes sense. When have you ever gotten as much out of something as you put into it. However, The extra energy ...

... Work depends on both force and distance: Wprof on cart = Fprof on cart∆x. Along path 1, the professor pushes the cart for less distance (as noted in part A), but he exerts a greater force, since he’s fighting gravity head-on (as noted in part B). By contrast, along path 2, the professor pushes with ...
