What is acceleration in physics?
0:02
Definition: acceleration is the rate of
0:05
change of velocity of an object with
0:07
respect to time. In simple words,
0:10
acceleration tells us how quickly an
0:12
object speeds up, slows down, or changes
0:15
direction. It is a vector quantity,
0:18
meaning it has both magnitude and
0:20
direction. Explanation: When an object
0:23
moves, its velocity speed with direction
0:26
may change. If the velocity increases,
0:28
the object is said to be accelerating.
0:31
If the velocity decreases, it
0:33
experiences deceleration negative
0:36
acceleration. Acceleration occurs not
0:38
only when speed changes, but also when
0:41
the direction of motion changes. For
0:44
example, when a car turns around a
0:46
curve, even at a constant speed. If
0:48
velocity changes at a uniform rate, the
0:51
acceleration is constant.
