Vectors and Scalars (Leaving Cert Physics): Flashcards

Measurable property with a number and unit

Numerical value and unit

Has magnitude only, no direction

Mass, time, energy, temperature, length, pressure

Use ordinary arithmetic (simple addition, subtraction)

Has both magnitude and direction

Displacement, velocity, force, acceleration, momentum

Magnitude of the vector

Direction of the vector

Single vector with same effect as all combined vectors

Sum of individual magnitudes

Difference between magnitudes

Direction of the larger vector

Zero (they cancel completely)
