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 do in a Free Body Diagram?

Back

The normal force acts perpendicular to the surface and supports the weight of the object resting on it.

Front

What is gravity in the context of Free Body Diagrams?

Back

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

Front

How many forces act on a stationary object on a flat surface?

Back

Typically, two forces: the weight of the object (downward) and the normal force (upward).

Front

What does it mean if an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, meaning all forces are balanced.

Front

What is friction in a Free Body Diagram?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface.

Front

What is the significance of the direction of arrows in Free Body Diagrams?

Back

The direction of arrows indicates the direction of the forces acting on the object.

Front

What happens to the forces in a Free Body Diagram when an object is accelerating?

Back

When an object is accelerating, the net force is not zero, meaning there is an unbalanced force acting on it.

Front

What is the role of air resistance in Free Body Diagrams?

Back

Air resistance is a type of friction that opposes the motion of an object moving through the air.

Front

How do you represent a push or pull force in a Free Body Diagram?

Back

A push or pull force is represented by an arrow pointing in the direction of the force.
