Free Body Diagrams Review

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 (F_N) 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 (F_f) in motion?

Back

Frictional force opposes the motion of an object, acting parallel to the surface.

Front

What does the applied force (F_A) refer to?

Back

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

Front

What is gravity in the context of Free Body Diagrams?

Back

The force that attracts a body toward the center of the earth, acting downward on the object.

Front

How do you determine if forces are balanced in a Free Body Diagram?

Back

Forces are balanced if the net force acting on the object is zero, meaning all forces cancel each other out.

Front

What is tension force (F_T)?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is momentum?

Back

The quantity of motion an object has, calculated as the product of its mass and velocity.

Front

What does a down-arrow in a Free Body Diagram typically represent?

Back

It usually represents the force of gravity acting on the object.
