The amount of motion is measured in? Joules x Seconds Meters X Seconds Kilograms x Meters / Seconds Newton x Meters

To determine the units representing the amount of motion, let’s analyze the options provided:

1. Joules × Seconds: Joules are a measure of energy, and seconds do not relate specifically to motion as a unit of measurement for motion alone.

2. Meters × Seconds: This represents a unit of velocity (meters per second), not the amount of motion itself.

3. Kilograms × Meters / Seconds: This is the unit for momentum, as momentum is defined as the product of mass (in kilograms) and velocity (in meters per second).

4. Newton × Meters: A Newton is a unit of force, and when multiplied by meters, it indicates work or energy, rather than directly measuring motion.

Analysis

• The amount of motion in physics is best represented by momentum, which is calculated as:

  $\text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v)$

  Hence, the proper unit of measurement for momentum is indeed $\text{kg} \cdot \frac{\text{m}}{\text{s}}$.

Conclusion

Based on this analysis, the correct answer is:

Kilograms × Meters / Seconds
