5 Free Body Diagrams

Front

What is a Free Body Diagram (FBD)?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What forces are typically represented in a Free Body Diagram?

Back

Forces such as gravity, normal force, friction, tension, and applied forces.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object, causing it to slow down or stop.

Front

What is the normal force?

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 formula for calculating net force?

Back

Net force = Sum of all forces acting on an object.

Front

If a box is pushed with a force of 10 N to the right and friction opposes with 4 N, what is the net force?

Back

Net force = 10 N - 4 N = 6 N to the right.

Front

What is the role of gravity in Free Body Diagrams?

Back

Gravity acts downward on objects, representing the weight of the object.

Front

How do you determine the direction of net force in a Free Body Diagram?

Back

The direction of net force is the same as the direction of the greater force acting on the 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 happens to the net force if two equal forces act in opposite directions?

Back

The net force is zero, resulting in no acceleration.
