The effect of an impulse force on the body is measured only in terms of is

Options

A. force on the object
B. moment of momentum
C. impulse
D. None of these

Answer

To solve the question regarding the effect of an impulse force on a body, we will analyze the concept of impulse and its relation to force.

### Step-by-Step Solution:

1. **Understanding Impulse**:
- Impulse is defined as the change in momentum of an object when a force is applied over a period of time. It is a vector quantity and is represented by the symbol \( J \).
- Mathematically, impulse can be expressed as:
\[ J = F \cdot \Delta t \]
where \( F \) is the average force applied, and \( \Delta t \) is the time duration over which the force acts.

2. **Characteristics of Impulsive Force**:
- An impulsive force is characterized by its large magnitude and the short duration over which it acts.
- This type of force causes a significant change in the momentum of the object it acts upon.

3. **Effect of Impulse on a Body**:
- The effect of an impulse force on a body is measured in terms of impulse itself, which is the product of the force and the time duration it acts.
- Thus, when an impulsive force acts on a body, it results in a change in momentum, which is quantified by the impulse.

4. **Conclusion**:
- Therefore, the effect of an impulse force on the body is measured only in terms of **impulse**.

### Final Answer:
The effect of an impulse force on the body is measured only in terms of **impulse**.
