Rotational Inertia and Angular Momentum
... Because the direction of something rotating is hard to determine, physicists say that the direction of angular momentum is in the plane of the rotation. If this wheel was rotating, we would say its angular momentum is pointed in this direction. So it would want to stay rotating in that direction. ...

... The input work is the input force multiplied by the length of the ramp (10 meters). If you set the input work equal to the output work, you quickly find that the input force is 50 newtons (Fd = F × 10 m = 500 J). The input force is one-tenth of the output force. For a frictionless ramp, the mechanic ...

Because the force is constant, the acceleration is constant, and the speed of the object (starting from rest) is given by v = at. With twice the acceleration, the object will arrive at speed v at half the time. ...
