What is a free body diagram?

Back

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

Front

What does the applied force represent in a free body diagram?

Back

The force that is applied to an object by an external source.

Front

What is the weight force in a free body diagram?

Back

The force due to gravity acting on an object, directed downward.

Front

Define normal force in the context of free body diagrams.

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 frictional force?

Back

The force that opposes the motion of an object in contact with a surface.

Front

What is tension in a free body diagram?

Back

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

Front

What is the direction of the gravitational force acting on an object?

Back

Straight down towards the center of the Earth.

Front

What is buoyant force?

Back

The upward force exerted by a fluid on an object submerged in it.

Front

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

Back

The normal force is less than the weight force and acts perpendicular to the surface of the incline.

Front

What is the role of the net force in free body diagrams?

Back

The net force is the vector sum of all forces acting on an object, determining its acceleration.
