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 role of gravity in a Free Body Diagram?

Back

Gravity is the force that pulls objects toward the center of the Earth, represented by a downward arrow.

Front

What is frictional force?

Back

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

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion, while unbalanced forces cause an object to accelerate.

Front

How do you calculate net force?

Back

Net force is the vector sum of all individual forces acting on an object.

Front

What does it mean if the net force is zero?

Back

It means that all forces acting on the object are balanced, resulting in no acceleration.

Front

What is weight force?

Back

The force of gravity acting on an object, calculated as mass times the acceleration due to gravity (W = mg).

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.
