Free Body Diagrams

Front

What is a Free Body Diagram (FBD)?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What forces are typically represented in a Free Body Diagram?

Back

Forces such as gravitational force, normal force, frictional force, applied force, tension force, and drag.

Front

What does the normal force represent in a Free Body Diagram?

Back

The force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object, causing it to slow down or stop.

Front

What is gravitational force?

Back

The force of attraction between two masses, commonly experienced as the weight of an object due to Earth's gravity.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest, preventing it from moving, while kinetic friction acts on an object in motion, opposing its movement.

Front

What is an applied force?

Back

A force that is applied to an object by a person or another object.

Front

What is tension force?

Back

The force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is drag force?

Back

The resistance force experienced by an object moving through a fluid (liquid or gas), opposing its motion.

Front

How do you determine the net force acting on an object?

Back

By vectorially adding all the forces acting on the object, taking into account their directions.
