What happens to acceleration when velocity increases?

Sure, as long as acceleration is positive, velocity increases, even if acceleration is decreasing (as long as it doesn’t reach zero). Likewise, as long as acceleration is negative, velocity decreases even if acceleration is increasing.Click to see full answer. Accordingly, why does acceleration decrease as speed increases?An acceleration can cause speed to increase, decrease, and even stay the same! Acceleration tells you the rate at which the velocity is changing. Because the velocity is a vector, you have to consider the changes to its magnitude and direction. This acceleration is negative because its direction is vertically downward.Also, does throwing an object down increase acceleration? When the force of air resistance equals the force of gravity, the ball will have reached terminal velocity. This means that when you throw the ball downwards, it starts off closer to terminal velocity. This means the acceleration will start off a little deteriorated. Subsequently, one may also ask, can velocity decrease while speed increases? Speed increases when velocity and acceleration have the same sign. In section B, the velocity is positive, but the slope is negative, so they have different signs and therefore the speed is decreasing. In section C, the velocity is negative and the slope is negative, meaning that the speed is increasing.Why does velocity increase?The reason why object keep increasing its velocity even though magnitude of force is decreasing is that the applied force has been converted to mechanical energy and been transformed to object. This energy keeps the object velocity increasing for some time and will eventually come to rest.
