WebOn the other hand if the car is moving to the right and is slowing down in velocity. The acceleration is working against the motion to slow the object down. In this case you have a negative acceleration. (vf-Vi)/t=Acceleration If your final velocity is smaller than your initial velocity, you will get a negative number for acceleration. WebAs going down is a positive force, the resultant force would be 700 + (-1000) = -300N. Here you have a negative force going downwards, meaning that you are decelerating (retarding). This is how acceleration is negative. … umich classes
