If the velocity and acceleration have opposite sign, then the object is slowing down If the velocity and acceleration have opposite sign, then the object is slowing down If the velocity is zero at an instant, then the acceleration should also be zero at that instant If the velocity is zero at an instant, then the acceleration should also be zero at that instant If the velocity is zero for a time interval, then the acceleration is zero at any instant within the time interval If the velocity is zero for a time interval, then the acceleration is zero at any instant within the time interval If the position and velocity have opposite sign, then the object is moving towards the origin If the position and velocity have opposite sign, then the object is moving towards the origin Finish
