Deceleration is the rate at which an object's velocity decreases. It is the opposite of acceleration, which is the rate at which an object's velocity increases.
Deceleration can be measured in terms of velocity change over time, or in terms of the force applied to the object. The unit of measurement for deceleration is meters per second squared (m/s²).
The main factors that affect deceleration are the object's mass, the force acting on the object, and the surface or medium through which the object is moving. Objects with greater mass or experiencing greater force will experience a greater deceleration, while objects moving through a medium with higher resistance (such as air or water) will also experience a greater deceleration.
Deceleration causes an object's velocity to decrease, which can result in slowing down or stopping the object's motion. If the deceleration is strong enough, it can also cause the object to change direction or even reverse its motion.
Yes, an object can have a negative deceleration, also known as acceleration. This occurs when an object's velocity is decreasing in the opposite direction of its motion, such as when a car is slowing down while moving forward.
