Vector quantities - Study guides, Class notes & Summaries

Scalars Quantities that are fully described by a magnitude alone. Vectors Quantities that are fully described by both a magnitude and a direction. Distance Scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement Vector quantity that refers to "how far out of place an object is" it is the object's overall change in position. Speed Scalar quantity that refers to "how fast an object is moving." Velocity V...

AQA GCSE Physics -Paper 2 100% Pass 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 object...
