Free Body Diagrams

What is a Free Body Diagram?

Back

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

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

What is the weight force in a Free Body Diagram?

Back

The force due to gravity acting on an object, directed downward towards the center of the Earth.

Front

What is frictional force?

Back

The force that opposes the relative motion of two surfaces in contact.

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

How do you determine the net force acting on an object using a Free Body Diagram?

Back

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

Front

What is the role of applied force in a Free Body Diagram?

Back

The external force applied to an object to cause it to move or accelerate.

Front

What is gravitational force?

Back

The attractive force between two masses, such as the Earth and an object, causing the object to fall.

Front

How does the normal force change when an object is on an incline?

Back

The normal force decreases as the angle of the incline increases, as it is equal to the weight component perpendicular to the surface.

Front

What happens to the normal force when an object is in free fall?

Back

The normal force is zero because there is no contact with a surface.
