Deceleration

Definition

Deceleration is the rate at which an object slows down. It is represented as a negative acceleration in physics and mathematics.

5 Must Know Facts For Your Next Test

1. Deceleration can be calculated using integration of velocity over time.
2. The Net Change Theorem can be used to determine the total change in velocity, including deceleration, over a given interval.
3. If acceleration is negative, it indicates that the object is decelerating.
4. In calculus, the integral of acceleration gives velocity, and the integral of velocity gives position.
5. Deceleration affects the area under the curve on a velocity-time graph; this area represents displacement.

Net Change Theorem:

$$\int_a^b f'(x) \ dx = f(b) - f(a)$$, it relates integrals to net change in quantities.
