Uniform Circular Motion 2
... In that case, you treat this case the same way you did in any dynamics problem, the sum of the forces matters...not any one force. So for instance, if we changed the prior example by having the object moving in a vertical circle, rather than a horizo ...

Vectors
... EXAMPLE 7 An airplane heads due east at 200 mph through a crosswind blowing due north at 30 mph, and the superposition (i.e., sum) of these two velocities is the airplane’s actual velocity vector. What is the airplane’s actual speed and direction? Solution: The heading velocity vector is 200, 0 an ...

Momentum and Its Conservation
... • Momentum is directly proportional to mass and momentum is directly proportional to velocity • Consider a 0.5-kg physics cart loaded with one 0.5-kg brick and moving with a speed of 2.0 m/s. Its momentum is 2.0 kg•m/s. If the cart was instead loaded with three 0.5-kg bricks, then the total mass of ...

... translation and rotation, v, # rw and a, # r a because of sliding. From equations (6) and (7) it can be observed that, while the sphere is acquiring angular speed, its linear speed gradually decreases. At the point when v,= rw. the sphere thereafter rolls at constant speed without slipping. At this ...
