Physics problem of senior one: If the acceleration direction is opposite to the displacement direction, the object will inevitably slow down. How to understand this sentence?
The displacement direction is consistent with the current speed direction. So the acceleration direction is opposite to the displacement direction, which means that the acceleration direction is opposite to the current speed direction, which is mathematically opposite in sign. If the defined speed direction is positive, the acceleration is negative.

According to V0+at=Vt, it is obvious that Vt
