Free Body Diagrams - Physics 101 / AP Physics 1 Review with Dianna Cowern

In this lesson, Diana introduces free body diagrams, a tool to analyze forces acting on objects. She explains fundamental forces, focusing on gravity, and demonstrates how to draw free body diagrams for various scenarios, including projectile motion and objects in elevators. The lesson explores air resistance, terminal velocity, and the Atwood machine experiment to measure gravitational acceleration. Key takeaways include understanding net forces and solving physics problems using free body diagrams.

Explain the concept of gravity as described in the lesson.

What are the four fundamental forces mentioned in the lesson?

What is a free body diagram and how is it used in physics?

How does air resistance affect falling objects according to the lesson?

What is terminal velocity and how is it related to the forces acting on a falling object?

Discuss the significance of measuring G (acceleration due to gravity) in the context of the lesson.

Describe the Atwood machine and its purpose in measuring gravity.

What are the implications of the results obtained from the Atwood machine experiment?

What factors can introduce errors in measuring gravitational acceleration?
