what is a simple pendulum a simple
0:02
pendulum is a weight called a bob
0:04
attached to the end of a string or Rod
0:06
that swings back and forth when set in
0:08
motion the string is fixed at one point
0:11
and the motion happens due to the force
0:12
of gravity it's called as simple because
0:15
it assumes no air resistance and the
0:17
string is massless and
0:19
inextensible how does a simple pendulum
0:21
Work One initial motion when the
0:25
pendulum is pulled to one side and
0:27
relaced gravity acts to pull the Bob
0:29
back toward its original position two
0:32
oscillation the Bob swings back and
0:34
forth in a regular pattern moving
0:36
through its lowest point the equilibrium
0:39
position this back and forth motion is
0:41
called
0:42
oscillation three forces involved
0:45
restoring Force gravity pulls the Bob
0:47
back to the center tension force the
0:50
string keeps the Bob moving in a curved
0:52
path key terms in simple pendular motion
0:56
amplitude a the maximum displacement
0:58
from the equilibrium position
1:01
period T the time it takes for the
1:02
pendulum to complete one full swing back
1:04
and forth frequency F how many
1:07
oscillations happen in 1 second length L
1:10
the distance from the fixed point to the
1:12
center of the Bob the formula for the
1:15
period the time period T of a simple
1:18
pendulum depends on its length and the
1:19
acceleration due to gravity J tal 2 Pi
1:23
squ root l a g longer pendulums take
1:27
more time to complete one
1:28
oscillation gravity affects the speed of
1:31
motion real world examples clocks use
1:35
pendulums to measure time
1:37
accurately scientists study pendulums to
1:40
understand Earth's gravity in essence a
1:42
simple pendulum demonstrates the beauty
1:44
of periodic motion and provides insights
1:46
into forces and energy in motion
