Mechanical Advantage and Simple Machines

This physics video tutorial explains the concept of mechanical advantage and simple machines such as the lever and the ramp. It contains plenty of examples and practice problems.

Here is a list of topics:
1. Lever - Input Force vs Output Force
2. Input Lever arm and output lever arm
3. Rotational Torque, Force, and Moment Arm
4. Magnification of Output Force Using Leverage
5. Mechanical Advantage of Levers - Output force divided by input force
6. Mechanical Advantage Calculations - Solving For Input Force and Output Distance - Formulas & Equations
7. Mechanical Advantage of the Ramp - Ramp Length over Height
8. Work required to lift up an object against gravity
9. Work required to push up a box along a ramp / incline
10. Power - Work divided by time - Rate of change of Energy with respect to time
11. Units of Work - Joules
12. Units of Power - Watts - Joules per second
