Introduction
Khan Academy is an educational website that provides free online classes in multiple subjects. It is an invaluable resource for students, especially those interested in science or math. One of the most helpful and well-explained lessons on Khan Academy is the free body diagram.
What is a Free Body Diagram?
A free body diagram is a visual representation of all the forces acting on an object. These diagrams show the magnitudes and directions of all the forces and are used to find the net force acting on an object. The net force is essential to determine whether an object will move, be at rest, or change direction.
The Process
To create a free body diagram, follow these simple steps:
1. Draw a dot to represent the object in question.
2. Draw an arrow for each force acting on the object.
3. Label the forces with their names and magnitudes and indicate their directions.
Example
For instance, suppose there is a book resting on a table. The weight of the book acts downwards, exerting a force of 10N on the table. Meanwhile, the table exerts an upward force of 10N on the book. To make the free body diagram, we would draw a dot representing the book and draw two arrows- one pointing upwards, representing the force exerted by the table, and the other pointing downwards, representing the book's weight. The arrows would be labeled with their magnitudes (10N) and directions.
Why are Free Body Diagrams Important?
Free body diagrams are essential for understanding physics problems since they enable us to visualize the forces acting on an object. They serve as a foundation for calculating the net force acting on an object and determining whether it will move or not. Understanding free body diagrams can lead to success in physics-related courses and careers.
Further Applications of Free Body Diagrams
Free body diagrams are used in other engineering fields as well. For instance:
1. In civil engineering- they are used to determine the forces on buildings by wind, earthquakes, or other environmental factors.
2. In aeronautical engineering- free body diagrams aid in understanding the forces acting on airplanes through air resistance and gravity.
