What is 15J converted into newton-metres? A 0.15 Nm B 1.5 Nm C 15 Nm D 150 Nm Your answer - OCR Gateway - GCSE Physics - Question 15 - 2023 - Paper 1

To convert joules (J) into newton-metres (Nm), we can use the relationship between work, energy, and torque.

1. Understanding the Units:

   • 1 Joule (J) is defined as the amount of work done when a force of 1 newton is applied over a distance of 1 metre. Thus,

   1 J = 1 Nm.

2. Performing the Conversion:

   • Given that we have 15 J, we can directly convert it by using the equivalence established above:

   15 J = 15 Nm.

3. Conclusion:

   • Therefore, 15 J is equivalent to 15 Nm.

Hence, the correct answer is C. 15 Nm.
