Understanding Acceleration | Force and Motion

Understanding Acceleration | Force and Motion | Form 4 Physics KSSM Chapter 2 Acceleration is defined as the rate of change of velocity. It is a measure of how fast the velocity change. In this video, we discussed 1. What is deceleration? 2. Does negative acceleration = Deceleration 3. What the negative acceleration really mean? Acceleration is a vector quantity, its sign (positive or negative) is determined by a. its direction b. rate of change of the speed If the speed of an object is increasing, the rate of change of the speed is positive, and if the speed of an object is decreasing, the rate of change of the speed is negative.
