On January 19, 2015, at the National Stadium in Warsaw, Poland, figure skater Olivia Rybicka-Oliver, at only 11 years old, shattered the Guinness World Record for the fastest spin on ice at 340 rpm. (a) What was her angular speed in rad/s? (b) Assume she comes to rest from this maximum angular speed in 3.2 s and calculate the number of rotations she completes during this time.

The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…

The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…
