Rotational Motion - Physics
Conservation of energy problem with rolling motion: A sphere, a hoop, and a cylinder, each with mass M and radius R, all start from rest at the top of an inclined plane and roll down to the bottom. Which object reaches the bottom first? Apply Conservation of Energy to determine v final. Largest v final will be the winner.

Operational Amplifiers and Negative Feedback
physicscourses.colorado.eduOperational Amplifiers and Negative Feedback Purpose This experiment shows how an operational amplifier (op-amp) with negative feedback can be used to make an amplifier with many desirable properties, such as stable gain, high linearity, and low output impedance. You will build both non-inverting and inverting voltage amplifiers using an LF356 ...
DIGITAL ELECTRONICS: LOGIC AND CLOCKS
physicscourses.colorado.eduDIGITAL LOGIC GATES The flow of digital signals is controlled by transistors in various configurations depending on the logic family (see H&H 8.09 for details). For most purposes, we can imagine that the logic gates are composed of several ideal switches with just two states: OPEN and CLOSED. The state of a switch is controlled by a digital signal.
Static Equilibrium - Physics
physicscourses.colorado.eduEquilibrium possible, but not guaranteed. Even though the net force is zero, the object might not be in static equilibrium. Here is a case (two forces acting on a bar) where the net force is zero, but the forces cause the object to rotate: In order to guarantee static equilibrium, we must have 1) net force = 0 AND 2) net torque = 0

www.nasa.govPotential energy (PE) is a stored form of energy that can produce motion, i.e. the “potential for motion.” Think of PE as stored energy that can become kinetic energy. You can calculate potential energy using an object’s mass and its height. PE is measured in Joules (J). PE = mgh where m = mass (kg), g = acceleration due to gravity
