An object in motion will slow down, or decelerate, if there are unbalanced forces acting upon it. See more. Consider a PED that is impacted against a rigid target at a horizontal orientation as shown in Figure 6.1.The impact force results in rapid deceleration of the device housing, including those points and edges of the PCB assembly that are attached to the device housing. It is always negative. We can easily define acceleration as “change in velocity”.As you understood from the definition there must be change in the velocity of the object. It is the rate at which an object slows down. An acceleration and deceleration sensor for use with safety devices in motor vehicles includes a reed switch and a movably mounted permanent magnet system which closes the switch during a collision. Pro Lite, Vedantu In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. A gradual decrease in speed or velocity is called as deceleration. So far, we have introduced three different aspects of motion. The exercises range from basic strength training to skilled drills and workouts.
