1. The problem statement, all variables and given/known data 1.) A brick has a mass of 2kg, how much (In Newtons) does it weigh? If you drop it, what is its acceleration? (ignoring air resistance)? 2. Relevant equations Im not sure 3. The attempt at a solution I found that 1kg = 10N, so 2kg =20 newtons, and I think that if you dropped it, since gravity is 10N (rounded up, which is what our teacher told us to do) then its acceleration would be 10N, but im not sure that's right.
