Weight and force are related concepts, but they are not the same. Here's a brief explanation of the differences between the two:
Force: Force is a vector quantity that can cause an object to change its state of motion, i.e., to accelerate, decelerate, or change direction. Force is described by magnitude and direction and is measured in units such as Newtons (N). There are several types of forces, like gravitational force, frictional force, applied force, and many more.
Weight: Weight is a specific type of force that results from the gravitational attraction between two objects, usually an object and a planet like Earth. The weight of an object depends on its mass and the gravitational acceleration acting on it (g). Weight is also a vector quantity and is measured in units like Newtons (N). Mathematically, weight is calculated as:
Weight = Mass × Gravitational acceleration (g)
For example, on Earth, the gravitational acceleration is approximately 9.81 m/s².
The difference between weight and force lies in the fact that weight is a specific force resulting from gravity, while force is a broader term encompassing any influence that causes an object to change its state of motion.
