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 they act.

Front

What are the types of forces that can act on an object?

Back

The types of forces that can act on an object include gravitational force, normal force, frictional force, tension force, and applied force.

Front

How does gravitational force affect an object?

Back

Gravitational force is the force of attraction between two masses. It pulls objects toward the center of the Earth or any other massive body.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with a surface. It acts perpendicular to the surface.

Front

What role does friction play in motion?

Back

Friction is a force that opposes the relative motion of two surfaces in contact. It can slow down or stop the motion of an object.

Front

What is tension force?

Back

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

Front

How does applied force differ from other forces?

Back

Applied force is a force that is applied to an object by a person or another object, as opposed to forces that arise from the object's interaction with its environment.

Front

What is the significance of the direction of forces in free-body diagrams?

Back

The direction of forces in free-body diagrams is crucial as it indicates how the forces interact with the object, affecting its motion and equilibrium.

Front

What is equilibrium in the context of forces?

Back

Equilibrium occurs when the net force acting on an object is zero, meaning all the forces are balanced and the object is either at rest or moving at a constant velocity.

Front

How can you determine the net force acting on an object?

Back

The net force can be determined by vector addition of all the individual forces acting on the object, taking into account their magnitudes and directions.
