Document Summary
Mass is the amount of matter in an object. We use a balance/scale to measure mass. What can force do: change the position of an object, change the speed of an object, change the direction of a moving object, change the shape of an object. Mass and weight are two different properties of matter. Mass: mass is a property of matter that explains how much matter is in an object, mass does not change when gravity changes. Weight: weight is a force which is calculated by multiplying the acceleration of gravity times the mass, weight can change when gravity changes. When it comes to gravity mass is the matter something has, though weight is gravity times mass (3) You"ve learnt that gravity pulls objects down towards the center of the earth. These two balls are the same size, but one has a much larger mass. Air resistance : the mass of an object is important when learning about air resistance.
