What's the difference between acceleration time diagram and velocity time diagram

Each point on the acceleration time graph corresponds to the acceleration value at each time. For example, a horizontal straight line indicates that the acceleration value has not changed; the velocity time graph represents the corresponding velocity at each time point, and the tangential slope on the curve is the acceleration value at the corresponding time point

2. According to this definition, if the velocity of an object increases from V1 to V2 in t time, the acceleration is V2 − v1t. An existing small ball starts to move at an acceleration of 3m / S2 for 2S, then the velocity of the small ball at the end of 2S is () A. 0B. 2m/sC. 3m/sD. 6m/s

7. What is the effect of velocity in physics When a physical object moves in a straight line at a speed of 0.1m/s under the action of tensile force, the friction force is 10N. If the object still moves in a straight line at a speed of 0.5m/s, what is the horizontal tensile force? How much is the friction force? Why? (excluding air resistance) Like this problem, the friction force and the pull force should be the same, both are 10N, but the speed is not determined by the pull force. The friction force has nothing to do with the speed, but the friction force is equal to the pull force, so what determines the speed
