AQA GCSE Physics -Paper 2 Scalar - ANSWERS-quantities with only magnitude such as speed, distance, time and mass. Vector - ANSWERS-quantities with a magnitude and direction e.g. acceleration, force momentum and weight. A vector quantity can be represented as an arrow, the size representing the magnitude and the direction, the direction. Non-contact force - ANSWERS-the objects are physically separate e.g. magnetism/gravity/electrostatic. 3 non-contact forces - ANSWERS-magnetism gravity electrostatic Contact force - ANSWERS-objects are physically touching . 3 contact forces - ANSWERS-friction resistance tension Gravity - ANSWERS-Weight is the force acting on an object due to gravity, it acts on an objects 'centre of mass' and is directly proportional to mass Weigh Equation - ANSWERS-Weight = mass x grav. field strength...
