IB Physics: 1 Measurement and uncertainties

Physics is all about deriving relationships between quantities so that we are able to make predictions. To derive relationships, we need to be able to measure the size of the quantities.A large ball of plasticine is heavier than a small one. To quantify the size we can measure the volume and to determine how heavy the ball is, we measure mass. If we did this for lots of different plasticine balls, we would find that...
