What are vector quantities in physics?
0:02
Vector quantities are physical
0:04
quantities that have both magnitude size
0:06
and direction. Vector quantities are
0:09
used to describe properties where
0:11
direction is important, such as force,
0:13
velocity, and displacement. They can be
0:16
represented by arrows in diagrams, where
0:19
the length of the arrow shows the
0:21
magnitude and the arrow head indicates
0:23
the direction. Imagine pushing a box
0:27
You need to know not only how hard you
0:30
push magnitude, but also which way you
0:34
Both pieces of information are essential
0:37
to describe the motion fully, which
0:39
makes it a vector quantity. Examples:
0:42
displacement of an object, velocity of a
0:44
moving car, force applied on a body,
0:47
acceleration of a particle, momentum of
0:50
an object asterisk asterisk.
