Mass and Weight are the same thing.
True
False
What is weight?
How much matter is in an object
The force of gravity on an object
The force that makes objects fall
The same thing as mass
If you take an object from Earth to the moon, what happens to its mass?
It increases because there's no air resistance

Newton's Third Law states -
Every action has an equal and opposite reaction
Force equals mass times acceleration
Objects in motion stay in motion and objects at rest stay at rest
Do or do not. There is no try.
