Momentum is a measure of

Options

A. weight
B. mass
C. quantity of motion
D. velocity

Answer

To solve the question "Momentum is a measure of?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Momentum**:
- Momentum is defined in physics as the product of an object's mass and its velocity. This relationship can be expressed mathematically as:
\[ \text{Momentum (p)} = \text{Mass (m)} \times \text{Velocity (v)} \]

2. **Identifying the Nature of Momentum**:
- Momentum is a vector quantity, which means it has both magnitude and direction. This is important because it distinguishes momentum from scalar quantities, which only have magnitude.

3. **Analyzing the Options**:
- Let's evaluate the options given in the question:
- Option 1: Weight - This is a measure of the force acting on an object due to gravity and is not related to momentum.
- Option 2: Mass - While mass is a component of momentum, it does not fully describe what momentum measures.
- Option 3: Quantity of Motion - This aligns with the definition of momentum, as it represents how much motion an object has.
- Option 4: Velocity - Similar to mass, velocity is a component of momentum but does not define it.

4. **Conclusion**:
- Based on the definitions and the analysis of the options, we conclude that momentum is indeed a measure of the "Quantity of Motion". Therefore, the correct answer is:
\[ \text{Option 3: Quantity of Motion} \]
