What is law of polygon of forces?

The Law of Polygon of Forces states that – if any number of coplanar concurrent forces can be represented in magnitude and direction by the sides of a polygon taken in order; then their resultant will be represented by the closing side of the polygon taken in opposite order”.

What forces are in equilibrium?

If an object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations. Thus, the net force is zero and the acceleration is 0 m/s/s. Objects at equilibrium must have an acceleration of 0 m/s/s.

What are various types of a force?

Or to read about an individual force, click on its name from the list below.

• Applied Force.
• Gravitational Force.
• Normal Force.
• Frictional Force.
• Air Resistance Force.
• Tension Force.
• Spring Force.

What is converse of the law of polygon of forces?

Arun. 3 years ago. Converse of triangle law of forces-“If there forces or vectors acting a point are in equilibrium than they can be represented both magnitude and direction by three sides of any triangle taken in order”.

Are there forces acting on an object at rest?

If an object is at rest, then there are no forces acting upon the object. It would take an unbalanced force to keep an object in motion at a constant velocity. It is the natural tendency of all objects to eventually come to a rest position.

What is the sum of all forces acting on a body called?

the net force
The vector sum of all of the forces acting on a body is a single force called the net force . If the net force is equal to zero, the object is said to be in equilibrium.

How many forces are there?

fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.

What are the 2 major types of forces?

Force is the external agent that produces motion. Basically, there are two main types of forces, contact forces, and non-contact forces.

What is polygon and parallelogram law of forces?

If two forces acting at a point are represented in magnitude and direction by the two adjacent sides of a parallelogram, then their resultant isrepresented in magnitude and direction by the diagonal passing through the point.

What is triangle law force?

TRIANGLE LAW OF FORCES: It states that if two concurrent forces are acting simultaneously on a body and are represented in magnitude and direction by the sides of a triangle taken in order, then the third side of the triangle represents their resultant of the forces in magnitude and direction taken in opposite order.

Is the converse of Polygon law of forces true?

THe converse of the polygon of forces in not true. A number of polygons can be found whose sides represent the forces, all the polygons are similar; but any polygon with its sides parallel to the forces will not represent them.
