What is the difference between mass and weight?

mass is how much matter is in an object, and weight is the gravitational pull on that object

mass and weight are the same

weight affects how much mass is in an object

weight is determined by how many atoms make up an object

Unit for mass

newton

m/s

m/s²

The force that one surface exerts on another when the two surfaces rub against each other

Speed

Force

Net force
