Free body diagrams

Front

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 role of frictional force in a free body diagram?

Back

The force that opposes the motion of an object, acting parallel to the surface of contact.

Front

Define thrust in the context of free body diagrams.

Back

The force that propels an object forward, often associated with engines or propellers.

Front

What is 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

How do you determine the net force in a free body diagram?

Back

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

Front

What happens to the net force when two forces act in opposite directions?

Back

The net force is found by subtracting the smaller force from the larger force.

Front

What is tension force 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

How does the direction of forces affect the net force?

Back

Forces in the same direction add together, while forces in opposite directions subtract from each other.

Front

What is buoyant force?

Back

The upward force exerted by a fluid on an object submerged in it, counteracting the weight of the object.
