acceleration in physics refers to the
0:02
rate at which an object's velocity
0:03
changes over time it measures how
0:06
quickly something speeds up slows down
0:10
Direction mathematically acceleration is
0:12
expressed as R is equal to DV over DT
0:17
where is acceleration DV is the change
0:20
in velocity and DT is the time taken for
0:22
the change positive acceleration means
0:25
an increase in speed negative
0:28
acceleration deceleration means me a
0:30
decrease in speed centripedal
0:32
acceleration occurs when an object
0:34
changes Direction while moving in a
0:36
circular path even if its speed remains
0:39
constant acceleration is a vector
0:41
quantity meaning it has both magnitude
0:43
and Direction its standard unit is m/s
0:47
squared for example when a car speeds up
0:50
from rest its velocity changes resulting
