... Two wheels initially at rest roll the same distance without slipping down identical inclined planes starting from rest. Wheel B has twice the radius but the same mass as wheel A. All the mass is concentrated in their rims, so that the rotational inertia's are I = mR2 . Which has more translational k ...

Summary of lesson
... When wind resistance equals the downward force of gravity, there are no net forces acting on the object. It stops accelerating. It moves with a constant downward speed called the terminal velocity. Although the force of gravity works on any object, the force of wind resistance is different. For exam ...
