While it is true that the force of gravity acts on all objects, the weight of an object depends on both its mass and the strength of the gravitational field it is in. Weight is the force exerted on an object due to gravity, and it is directly proportional to an object's mass.
The weight of an object can be calculated using the formula:
Weight = mass × acceleration due to gravity
The acceleration due to gravity is approximately the same on the surface of the Earth, which is about 9.8 meters per second squared (9.8 m/s²). However, the mass of an object determines how much matter it contains, and therefore, it affects the force of gravity acting on it.
According to Newton's second law of motion, force is equal to mass multiplied by acceleration. In the case of gravity, the force is the weight, and the acceleration is the acceleration due to gravity. So, the weight of an object is directly proportional to its mass.
In simple terms, if you have two objects with different masses, the one with greater mass will have a greater weight because the force of gravity acting on it is greater. The mass of an object determines how much matter it contains, while weight depends on both mass and the strength of the gravitational field.
It's important to note that weight is not the same as mass. Mass is a measure of the amount of matter in an object and remains the same regardless of the gravitational field, while weight depends on the gravitational force and can vary depending on the strength of that force.
