The relationship between the velocity at the middle position and the velocity at the middle time If the object moves from a to B in a straight line with uniform speed change, the velocity at the middle position is V1, and the velocity at the middle moment is V2, then the relation of V1V2 is () A. When the object moves at a constant speed, V1 is greater than v2 B. When the object is accelerating uniformly, V1 is less than v2 C. When a body moves at a constant speed, V1 equals v2 D. When the object decelerates uniformly, V1 is greater than v2 Is a multi topic, will be the process!

If the object is moving in a straight line with uniform acceleration, the V - t image is shown in Figure 1, v 1 & gt; & nbsp; V 2; if the object is moving in a straight line with uniform deceleration, the V - t image is shown in Figure 2, v 1 & gt; & nbsp; V 2; if the object is moving in a straight line with uniform velocity, the velocity at any position and at any time is equal, so the correct answers are a, C and D
