Answer : 1. "Newton is a unit of force."
Explanation :
1. Newton is the SI unit of force. It is a unit force that causes an acceleration of one meter per second on one kilogram of mass.
- Force can be defined as:
Force =Mass x Acceleration
2. Joule is the SI unit of energy and work. It is the unit work done by one Newton force over a distance of one meter.
- Energy can be defined as:
Energy = Work x Time
