Delve into this chapter to find out about the mechanics of physics that explain how objects move and what forces affect their movement. Get higher grades, prepare for an upcoming test, or just enhance your general knowledge about the field of physics.

Mechanics of Physics - Chapter Summary

The field of physics explores and studies the natural world, and to do so requires an understanding of the mechanics of physics, which are the forces, formulas, and other concepts that explain how objects move. The lessons in this chapter elaborate on these individual mechanics, as well as associated laws, contributions from scientists, and related mathematical equations.

You can use this chapter to learn about these topics from the ground up, or if you already know about these topics, use our lessons as a study guide to help you brush up on the important details. Although the lessons have been prepared in a specific order, you are not required to watch them in that order. Each lesson is self-contained, so you can watch the lessons individually. We keep our lessons short and focused on a single main topic, making it easier to navigate your way through the chapter. By the end of this chapter, you should understand:

  • The definition of velocity and speed and ways to use formulas to determine them
  • How mechanics affect objects
  • How Newton's laws explain principles of gravity, mass, and weight
