The unit used to measure force in the metric system

• Newton (N)

• weight (lb)

• weight (ounce)

• kilogram

Any two masses attract each other depending on how big the masses are and how far they are from each other

• Law of Conservation of Energy (Conservation)

• acceleration

• Newton's Law of Universal Gravitation

• Newton's 2nd Law
