The weight of an object

Options

A. is the quantity of the matter it contains
B. refers to its inertia
C. is same as its mass but is expressed in different units
D. is the force with which it is attracted to wards the earth

Explanation

To determine the weight of an object, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Weight**:
- Weight is defined as the force with which an object is attracted towards the Earth due to gravity.

2. **Use the Formula for Weight**:
- The weight (W) of an object can be calculated using the formula:
\[ W = m \cdot g \]
where:
- \( W \) is the weight,
- \( m \) is the mass of the object,
- \( g \) is the acceleration due to gravity (approximately \( 9.81 \, \text{m/s}^2 \) on the surface of the Earth).

3. **Identify the Options**:
- The question provides four options regarding the definition of weight. We need to evaluate these options to find the correct one.

4. **Evaluate Each Option**:
- **Option 1**: "The quantity of the matter it contains."
- This describes mass, not weight, so it is incorrect.
- **Option 2**: "The force with which it is attracted towards the Earth."
- This is the correct definition of weight.
- **Option 3**: "The measure of the gravitational pull on an object."
- This is somewhat vague but can be interpreted as weight; however, it is not as precise as option 2.
- **Option 4**: "The force with which it is attracted towards the Earth."
- This is the correct answer.

5. **Conclusion**:
- The correct answer is that the weight of an object is the force with which it is attracted towards the Earth.

### Final Answer:
The weight of an object is the force with which it is attracted towards the Earth.
