This problem is about the average net torque on a wheel when we know the change in its angular speed, moment of inertia and change in time.

This problem is about what happens to angular speed, tangential acceleration and centripetal acceleration for a satellite in a circular orbit.

This is a review of all of the dimensions used in AP Physics C - Mechanics. Okay, maybe it doesn't cover some of the basic dimensions, however, if you don't know that linear velocity is in furlongs per fortnight, then I probably can't...

That’s right, we actually measure the rotational inertia of a bicycle wheel. How cool is that?

What is the closest to the end of a 93 g uniform meterstick you can place a 200.0 g object and have the system stay balanced? The meterstick is supported at the 20.0 cm and 80.0 cm marks.

This nugget explains the kinematic of rotational motions and three equivalent of motion for bodies in a rotational motion.

Using Uniformly Accelerated Motion (UAM) as a framework to learn about Uniformly Angularly Accelerated Motion (UαM). Just like UAM, UαM has 5 variables, 4 equations and if you know 3 of the UαM variables, you can determine the other 2...

A rope is wrapped around a bicycle wheel with a rotational inertia of 0.68MR^2. The wheel is released from rest and allowed to descend without slipping as the rope unwinds from the wheel. In terms of g, determine the acceleration of the...

The bar is purely rotating about the pin support, so if we view the bar as rotating around the pin, then the translational component of the kinetic energy will be 0 (because the pin is not moving). The change in gravitational potential...

This is one dynamics example problem you could expect to see on your exam. It tests a variety of different topics.<br/>
i) a_x =<br/> 2.21 m/s^2
ii) V_2 = 2.97 m/s downwards (onc<br/>e moved down 2 meters)
iii) T_1 = 40.38N and T_2 = 76.01N
