how do positive and negative acceleration differ? 1. positive acceleration represents an object speeding up; negative acceleration represents an object slowing down 2. positive acceleration moves North or east; negative acceleration moves south or west 3. positive acceleration occurs when there is more velocity than speed; negative acceleration occurs when there is less velocity than speed. 4. positive acceleration occurs when an object changes its speed but not its direction; negative acceleration occurs when an object changes both its speed and direction
