Question

Is it possible that an object moving with decreasing speed have constant acceleration?

Answer 1

Answer:The velocity vector is constant in magnitude but changing in direction. Because the speed is constant for such a motion, many students have the misconception that there is no acceleration. ... For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating

Answer 2

Yes, that's right, a change in the direction of motion results in an acceleration even if the moving object neither sped up nor slowed down. ... Acceleration occurs anytime an object's speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous.
