Acceleration:
Acceleration is the rate at which an object's velocity changes over time. It is a vector quantity, meaning it has both magnitude and direction.
Uniform Acceleration:
This occurs when an object’s velocity changes at a constant rate. An example is a car accelerating at a constant rate, increasing its speed by the same amount every second.
Non-Uniform Acceleration:
Here, the rate of change of velocity is not constant. The object’s acceleration varies over time. For example, a car speeding up and slowing down at different rates as it navigates through traffic.
Deceleration:
Deceleration is simply negative acceleration. It occurs when the velocity of an object decreases over time. Like acceleration, it is also a vector quantity and acts in the direction opposite to the velocity. For example, when you apply brakes in a car, the car slows down, which is deceleration.
