A force is made up of two quantities—a magnitude and a _____

Options

A. speed
B. vector
C. height
D. direction

Answer

To solve the question "A force is made up of two quantities—a magnitude and a _____", we can follow these steps:

### Step 1: Understand the Concept of Force
- Force is defined as an interaction that causes an object to change its velocity (which includes starting, stopping, or changing direction).
- Mathematically, force is expressed as the product of mass and acceleration (F = m × a).

### Step 2: Identify the Nature of Force
- Force is classified as a vector quantity. This means it has both magnitude and direction.
- Magnitude refers to the size or amount of force, while direction indicates the line along which the force acts.

### Step 3: Analyze the Options Given
- The options provided are: speed, vector, height, direction.
- We need to identify which of these options represents the second quantity that, along with magnitude, defines a force.

### Step 4: Eliminate Incorrect Options
- Speed: This is a scalar quantity and does not represent the direction of force.
- Vector: While force is a vector quantity, this term does not represent the second quantity we are looking for.
- Height: This is not related to the definition of force.
- Direction: This is the correct term that, along with magnitude, fully describes a force.

### Step 5: Conclusion
- Therefore, the answer to the question is "A force is made up of two quantities—a magnitude and a direction."

### Final Answer:
A force is made up of two quantities—a magnitude and a **direction**.
