The weight of a body is equal to

Options

A. mass x gravity
B. mass/gravity
C. gravity/mass
D. none of these

Answer

To determine the weight of a body, we can follow these steps:

### Step 1: Understand the Definitions
- **Mass**: It is the measure of the amount of matter in an object. It is usually measured in kilograms (kg).
- **Weight**: It is the force exerted by gravity on that mass. Weight is calculated as the mass of the object multiplied by the acceleration due to gravity.

### Step 2: Know the Formula for Weight
The formula for calculating weight (W) is:
\[ W = m \times g \]
where:
- \( W \) = weight of the object (in Newtons, N)
- \( m \) = mass of the object (in kilograms, kg)
- \( g \) = acceleration due to gravity (approximately \( 9.81 \, \text{m/s}^2 \) on Earth)

### Step 3: Identify the Correct Option
From the given options:
1. Mass into gravity (correct)
2. Mass divided by gravity
3. Gravity over mass
4. Nanopiece

The correct answer is the first option: **mass into gravity**.

### Step 4: Example Calculation (Optional)
If we have an object with a mass of 20 kg, we can calculate its weight as follows:
\[ W = 20 \, \text{kg} \times 9.81 \, \text{m/s}^2 = 196.2 \, \text{N} \]
This shows how to apply the formula to find the weight of an object.

### Conclusion
Thus, the weight of a body is equal to mass multiplied by the acceleration due to gravity.
