The force exerted by the earth on a body is called _____________ of the body.a)massb)weightc)pressured)forceCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Mass is the total amount of matter present in a body where as pressure is the the force applied on a particular area and force is the interaction which changes the the state of motion of a body and weight is the amount of force acting on a body which relates to its mass and acceleration due to gravitational pull of Earth so we all know that the force exerted by the earth is the gravitational force but when it acts on the body it becomes the weight of the body

Answer

Gravitational

Answer

Ans:--- Gravitational force of attraction acting between all matter ..On Earth all bodies have a Wight, or downwards force of gravity, proportional to their mass , which Earth's mass exerts on them.

Answer

As the gravitational force is different in different places ..for example - ..Moon , it do not have the same amount of gravituonal force as it is on earth ..when the gravitational force reacts on any object it has a weight . The weight is the resultant of the gravitational force which attracts objects towards its centre.

Answer

Weight
Weight is the force exerted by the Earth on a body. It is a measure of the gravitational force acting on an object and is directly proportional to the mass of the object. The weight of an object depends on the strength of the gravitational field at the location of the object.

Mass
Mass, on the other hand, is a measure of the amount of matter in an object. It is a scalar quantity and does not depend on the location of the object. Mass is constant and does not change with the strength of the gravitational field.

Explanation
When we say that the force exerted by the Earth on a body is called weight, it means that weight is the gravitational force acting on the body due to the Earth's mass. This force is responsible for the body's downward acceleration and can be calculated using the formula: weight = mass × acceleration due to gravity.

The weight of an object can be measured using a spring balance or a weighing scale. These devices measure the force exerted by the object on them, which is equal to the weight of the object.

Weight is a vector quantity and has both magnitude and direction. The direction of the weight is always towards the center of the Earth. In other words, weight always acts downwards.

Difference between Weight and Mass
The key difference between weight and mass is that weight is a force while mass is a measure of the amount of matter in an object. Other differences include:

- Weight depends on the strength of the gravitational field and varies with location, while mass is constant.
- Weight is measured in newtons (N), while mass is measured in kilograms (kg).
- Weight is a vector quantity, while mass is a scalar quantity.
- Weight can change if the gravitational field changes, while mass remains the same.

In summary, weight is the force exerted by the Earth on a body, while mass is a measure of the amount of matter in an object. Weight depends on the strength of the gravitational field, while mass is constant.
