1
Q
scalar quantity
A
has magnitude (size) but no direction
2
Q
vector quantity
A
has both magnitude (size) and a specific direction
3
Q
scalar vs. vector
A
scalar only has magnitude, whereas vector has direction as well
4
Q
examples of some scalar and vector quantities:
A
scalars: distance, speed, mass, energy
vectors: disolacement, velocity, acceleration, force, weight, momentum
5
Q
velocity
A
speed in a stated direction
6
Q
speed =
A
distance over time
