Detailed explanation-1: -The most common definition of weight found in introductory physics textbooks defines weight as the force exerted on a body by gravity. This is often expressed in the formula W = mg, where W is the weight, m the mass of the object, and g gravitational acceleration.
Detailed explanation-2: -Over small distances, when the curvature of the earth’s surface can be neglected, the direction of the gravitational force vector is also nearly constant. It points straight downward towards the center of the earth. The force of gravity acting on an object is called its weight.
Detailed explanation-3: -Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth.
Detailed explanation-4: -On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
Detailed explanation-5: -Answer and Explanation: The force exerted on a body by gravity is called weight.
