In physics, what is the term used for the push or pull acting on a body?

The term that describes the push or pull acting on a body is force. In physics, force is defined as an interaction that, when unopposed, will change the motion of an object. It is measured in newtons and can be the result of various interactions like friction, tension, or gravitational pull. Understanding force is fundamental in analyzing how objects move and interact with one another, making it a crucial concept in both physics and related fields.

Gravity and weight are often confused with force, as they both relate to the influence of mass and gravitational fields. However, gravity specifically refers to the attraction between two masses, while weight is the force exerted on an object due to gravity acting on its mass. Energy, on the other hand, is the capacity to do work, which can be influenced by forces but is a different concept altogether. Therefore, force is the most accurate term to describe a push or pull on a body.
