Answers1. 9.8*2 Kg = 19.6 N Therefore the cookie weighs 19.6 newtons
2. 1000 grams = 1 kilogram 500 grams = .5 kilograms .5 Kg*9.8 = 4.9 N Therefore, the keyboard weighs 4.9 Newtons 3. 20/9.8 = 2.04 Kg Therefore the shopping car's mass is 2.04 Kilograms 4. Mass is the quantity of matter in an object, and weight is the force that is acted upon an object due to the force of gravity 5. The most common contact force is friction.
