What is third Newton's law of motion?
0:02
Third Newton's law of motion states that
0:04
for every action there is an equal and
0:07
opposite reaction. This law explains
0:10
that forces always occur in pairs. When
0:13
one object exerts a force on another
0:15
object, the second object simultaneously
0:18
exerts an equal force in the opposite
0:21
direction on the first object. These
0:23
action and reaction forces act on
0:26
different objects, so they do not cancel
0:28
each other out. This principle helps
0:30
explain many everyday phenomena
0:33
involving interaction between objects.

Imagine pushing a wall. The wall pushes
0:38
back on you with an equal force in the
0:40
opposite direction even though it does
0:43
not move. Examples: recoil of a gun when
0:46
fired. Walking, where your foot pushes
0:48
the ground and the ground pushes you
0:50
forward. A rocket launching due to
0:53
expelled gases pushing downward.

Swimming, where you push water backward
