Through interactive practice problems and examples, students calculate the amount of work done by forces.

In the following interactive students will begin to explain the human body's consumption of energy when at rest vs. when engaged in activities that do useful work. They will also calculate the conversion of chemical energy in food into...

By the end of this section, you will be able to explain the human body's consumption of energy when at rest versus when engaged in activities that do useful work and to calculate the conversion of chemical energy in food into useful work.

Through illustrated examples and practice problems, students apply the relationship between work and mechanical energy change to a variety of motion scenarios in order to test our understanding.

In this interactive exercise, explore the quantitative relationship between work and mechanical energy in situations in which there are no external forces doing work.

In this module, students learn how work, energy, and power are related to one another in various ways. They also learn about collisions and the conservation of momentum.

Through illustrated examples and interactive examples, students learn about the two categories of forces are referred to as internal forces and external forces.
