Amps and current were first thought of with Ben Franklin, so the convention is of positive charge moving. Ohm's law is useful when it's applicable (which is likely throughout this class). V = …

## What is the Moment of Inertia?

We looked at rotational moment and the moment of inertial as well as some connected ideas. The Greek letter omega stands for angular velocity, alpha stands for angular acceleration. Capital L stands …

## Car on Five Degree Incline with Friction, Energy Conversion

We started by looking at a problem with a car at the top of a five degree incline that rolled for 60 m. The force due to friction was given and the problem was to determine the velocity at the bottom …

## Tutoring Physics, Impulse & Change in Momentum

We looked at problems involving impulse and change in momentum. There were three forms of impulse that were all equivalent, you choose which one based on the information you have. Change in momentum, …

## Tutoring Physics, Centripetal Acceleration

We looked at problems involving centripetal acceleration, movement in circular paths. The new equation we used was that a(centripetal) = v^2/r Looked at three problems. Also had to convert units a …

## Tutoring Newtonian Physics, Day 1

We started by talking a little about what Newtonian physics is including what the units of force are and how you can break down Newtons in kg, s, and m. Went into some problems include motion …
