The strength of force is expressed by?

Options

A. weight
B. mass
C. magnitude
D. longitudinal force

Answer

To answer the question "The strength of force is expressed by?", we can break it down into the following steps:

### Step 1: Understand the Concept of Force
Force is a physical quantity that can cause an object to change its state of motion. It is important to recognize that force has both magnitude and direction.

### Step 2: Identify the Characteristics of Force
Force is classified as a vector quantity. This means that it has two main characteristics:
- **Magnitude**: This refers to the strength or size of the force. It is usually measured in Newtons (N).
- **Direction**: This indicates the direction in which the force is applied.

### Step 3: Define Magnitude
Magnitude is a numerical value that represents the strength of the force. For example, if a force is described as 5N, it means that the force has a strength of 5 Newtons.

### Step 4: Conclusion
Thus, the strength of force is expressed by its **magnitude**. This tells us how strong the force is, while the direction tells us where the force is applied.

### Final Answer
The strength of force is expressed by its **magnitude**.
