- Write Units of Velocity and acceleration in [LMT] system
- Assume the formula: Force = mass x acceleration and write the LMT unit for Force
- We have discussed some fundamental ideas and questions like:
“What is one meter?” “what is ‘natural’ in natural numbers?”
Discuss and explain these ideas to your friends and parents.
