Meaning of force?

Force is a physical quantity that describes the interaction between objects or particles that causes a change in their motion or shape. It is typically measured in units such as newtons and is characterized by its magnitude and direction. Forces can be classified as contact forces, such as friction or tension, or as non-contact forces, such as gravity or electromagnetic forces.

Force is a physical quantity that describes the interaction between any two objects. It is a vector quantity, meaning that it has both magnitude (strength) and direction. The magnitude of the force is measured in newtons (N), and the direction of the force is indicated by a vector arrow.

Forces can be classified into two types: contact forces and non-contact forces. Contact forces are forces that act between two objects that are in physical contact with each other. Examples of contact forces include friction, tension, and normal force. Non-contact forces are forces that act between two objects that are not in physical contact with each other. Examples of non-contact forces include gravity and magnetism.

Forces can be used to change the motion of an object. For example, a force can be used to accelerate an object, decelerate an object, or change the direction of an object's motion. Forces can also be used to deform an object or to cause an object to vibrate.
