Power

The Power Video Tutorial discusses the concept of power and distinguishes it from work. The meaning of a power rating is explained and related to work and time. The equation relating power to work and time and to force and velocity is explained and used in two examples.

The video lesson answers the following questions:

1. How are power and work different than one another?
2. How do you analyze physical situations to determine the power delivered by an object?

Minds On Physics, Work and Energy module, Mission WE2
Minds On Physics (affectionately known as MOPs) is like good medicine. At times it may not taste good but it's exactly what the doctor ordered. Give this one a try and seal up your understanding of power.

The Calculator Pad, Work and Energy Problem Set, Problems #6-9
If your Physics course puts an emphasis on algebraic problem-solving, then you need to get acquainted with our Calculator Pad - a collection of problem sets with answers and audio-guided solutions. This problem set contains 4 problems on Power.
