Scalars & Vectors Flashcards

All 6 cards in this deck

What is a scalar quantity?: A quantity that has only size (magnitude), with no specific direction.
What is a vector quantity?: A quantity that has both size (magnitude) and a specific direction.
Name four vector quantities met in GCSE physics.: Displacement, velocity, acceleration, force (also weight and momentum).
Name four scalar quantities met in GCSE physics.: Distance, speed, mass, energy.
True or false? Energy is a vector quantity.: False. Energy is a scalar — it has size only.
What is the difference between distance and displacement?: Distance is how far an object has moved (a scalar). Displacement is the straight-line distance from start to finish, with its direction (a vector).
