If the velocity and acceleration have opposite signs then If the velocity is positive and the acceleration negative the object speeds up if the velocity is negative and I the acceleration is positive then the object speeds up the object will speed up the object will slow down

If the velocity and acceleration have opposite signs, then the object will slow down.<br /><br />Explanation:<br />- When the velocity is positive and the acceleration is negative, the acceleration is acting in the opposite direction to the velocity. This means the object will slow down.<br />- Similarly, when the velocity is negative and the acceleration is positive, the acceleration is acting in the opposite direction to the velocity. This means the object will also slow down.<br /><br />In both cases, the acceleration is working against the direction of the velocity, causing the object to slow down.
