Scalars & Vectors (AQA GCSE Physics): Flashcards

Magnitude (size) only, no direction

Mass, temperature, speed, energy, distance, time

Both magnitude and direction

Displacement, weight, force, velocity, acceleration, momentum

By arrows

Magnitude of the vector

Direction of the vector

Non-negative

Positive or negative depending on direction

Speed: magnitude only; velocity: includes direction

Changing velocity (direction changes)

Direction changes, so velocity changes
