Free Body Diagrams

Front

What is a free body diagram?

Back

A free body diagram is a graphical representation used to visualize the forces acting on an object. It shows the object as a dot and the forces as arrows pointing in the direction of the force.

Front

What does the length of the arrow in a free body diagram represent?

Back

The length of the arrow in a free body diagram represents the magnitude of the force acting on the object.

Front

How do you calculate net force?

Back

Net force is calculated by vectorially adding all the individual forces acting on an object. If forces are in the same direction, they are added; if they are in opposite directions, they are subtracted.

Front

What is the net force acting on an object at rest?

Back

The net force acting on an object at rest is 0 N, as there is no acceleration.

Front

What is the significance of a net force of 0 N?

Back

A net force of 0 N indicates that the object is in equilibrium, meaning it is either at rest or moving at a constant velocity.

Front

If an object has a weight of 1 N and is in free fall, what is the net force acting on it?

Back

The net force acting on the object in free fall is equal to its weight, which is 1 N.

Front

What does a rightward gravitational force of 100 N indicate in a free body diagram?

Back

A rightward gravitational force of 100 N indicates that there is a force acting on the object in the right direction, which may be due to another force overcoming gravity.

Front

What is the role of gravity in free body diagrams?

Back

Gravity is a force that acts downward on objects, and it is typically represented as an arrow pointing downwards in free body diagrams.

Front

How do you represent multiple forces acting on an object in a free body diagram?

Back

Multiple forces are represented by drawing arrows for each force, originating from the object and pointing in the direction of each force.

Front

What is the net force if two forces of 50 N and 200 N act in the same direction?

Back

The net force would be 250 N in the direction of the forces.
