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?

Back

It acts perpendicular to the surface an object is in contact with, supporting the weight of the object.

Front

What is friction?

Back

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

Front

What is weight force?

Back

The force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (F = mg).

Front

What is an applied force?

Back

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

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 buoyant force?

Back

The upward force exerted by a fluid on an object immersed in it, counteracting the object's weight.

Front

What is thrust?

Back

The force that propels an object forward, often produced by engines or propellers.

Front

How do you identify forces in a Free Body Diagram?

Back

By drawing arrows representing the magnitude and direction of each force acting on the object.

Front

What is the relationship between mass and weight?

Back

Weight is the force due to gravity acting on an object's mass (Weight = mass × gravity).
