What is acceleration? Definition:
0:02
Acceleration is the rate at which the
0:04
velocity of an object changes with time.
0:08
Explanation: An object accelerates when
0:10
it speeds up, slows down, or changes
0:13
direction. It is a vector quantity,
0:16
meaning it has both magnitude and
0:18
direction. For example, when a car
0:21
increases its speed on a highway, it is
0:24
positive acceleration. When it slows
0:27
down at a red light, it is negative
0:29
acceleration, often called deceleration.
0:32
Imagine, imagine riding a bicycle. If
0:34
you start pedaling harder, the bike
0:36
speeds up. That's acceleration. If you
0:39
apply the brakes, the bike slows down.
0:42
That's also acceleration, but in the
0:44
opposite direction. In simple terms,
0:47
acceleration is how quickly something
