Acceleration For its velocity to change, an object must accelerate. An object accelerates whenever its speed or direction or both change. Acceleration may be positive (increasing speed) or negative (decreasing speed). The 3 Types of Acceleration Speeding Up Slowing Down Turning Acceleration at Consta...
Acceleration is defined as the change in velocity over time. Any time an object's velocity is changing, we say that the object is accelerating. This brings up an important point. In common language, when things speed up, we say that they are "accelerating", and, when they slow down, we...

Velocity is the rate of change of the displacement of an object, whereas acceleration is the rate of change of its velocity. The velocity of an object can be calculated from the displacement-time graph of the object, and its SI unit is m/s. On the other hand, the acceleration of an ...

A curved slope means that the acceleration is changing – the object has non-uniform acceleration. Check carefully whether a graph is a speed-time graph or a distance-time graph. On true speed–time graphs, the speed has only positive values. On velocity–time graphs the velocity can be...
acceleration是加速度, velocity是速度,speed是位移,知道意思应该就没问题了吧
