Scalar quantities with only magnitude such as speed, distance, time and mass. Vector 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 the objects are physically separate e.g. magnetism/gravity/electrostatic. 3 non-contact forces magnetism gravity electrostatic Contact force objects are physically touching ...
